Abstract
The tannery effluent from the wet finishing stage is a complex, highly charged rejected of organic and mineral matter. It has variable characteristics over time and is not readily biodegradable. Its physicochemical treatment by adsorption on the smectitic clay of Khlédia proves to be effective. The reduction of dye, BOD, COD, heavy metals are remarkable. The decrease of the conductivity is due to the phenomenon of the cations adsorption on the negatively charged support colloids.

A Brief Comparative Study on Removal of Toxic Dyes by Different Types of Clay
Dyes and Pigments - Novel Applications and Waste Treatment, 2021
Increasing amount of organic dyes in the ecosystem particularly in wastewater has propelled the search for more efficient low-cost bio adsorbents. Different techniques have been used for the treatment of wastewater containing toxic dyes such as: biological degradation, oxidation, adsorption, reverse osmosis, and membrane filtration. Among all these processes mentioned, adsorption with low cost adsorbents has been recognized as one of the cost effective and efficient techniques for treatment of industrial wastewater from organic and inorganic pollutants. Clays as material adsorbents for the removal of various toxic dyes from aqueous solutions as potential alternatives to activated carbons has recently received widespread attention because of the environmental-friendly nature of clay materials. This chapter presents a comprehensive account of the techniques used for the removal of industrial cationic and anionic dyes from water during the last 10 years with special reference to the ad...
Pre-treated Moroccan natural clays: application to the wastewater treatment of textile industry
DESALINATION AND WATER TREATMENT, 2021
The current study was carried out to examine the pre-treated Moroccan natural clays for the removal of methylene blue dye by the adsorption method. The adsorbent was characterized by X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy. After performing the experiment and analyzing the data, it was found that the optimum conditions for fixing yellow marl and kaolinite (0.05 mm) are 93%-98%. The adsorption kinetics of methylene blue on kaolinite (C = 300 ppm, 50 µm) and on yellow marl (C = 500 ppm, 50 µm) is very efficient. Kaolinite adsorbed better towards basic pH. The equilibrium adsorbed amounts reached 27.5 mg g-1 for yellow marl and 16 mg g-1 for kaolinite. Application of the membranes developed in the treatment of dyes shows that the rejection rates obtained depend on the charge of the ions, their sizes, the charge of the membrane linked to the pH of the filtered solution. The difference in adsorption capacity between the two clays studied is due to the percentage of the clay phase in each and its composition.

The aim of the present work was to study the application of natural clays to remove a cationic dye (methylene blue (MB) chosen as a pollutant model) from wastewater. Rhassoul-clay and Red clay investigated in this study were extracted from two different sites in Morocco. These clays have different swelling properties. A comparison of their affinity towards cationic dye help to understand the limiting factors controlling the adsorption process. Rhassoul clay and Red clay were characterized using powder X-ray diffraction, Scanning Electron Microscopy, Xray Fluorescence spectroscopy and surface area measurement (BET). The adsorption capacities of the solids were measured using batch sorption studies as a function of contact time, pH, temperature and initial concentration. Pseudo-second-order model and intraparticle diffusion model were applicables to describe the MB adsorption on both adsorbents. Langmuir and Freundlich isotherms were employed to determine adsorption mechanism. According to the results, the Langmuir model was more suitable to describe MB adsorption on both adsorbents. The maximum monolayer adsorption evaluated with this model is 166.7 mg g −1 and 18.7 mg g −1 for Rhassoulclay and Red clay, respectively. The temperature exhibited a positive effect on MB adsorption. According to Gibbs energy and enthalpy, the adsorption process was spontaneous and endothermic for both clays, but was more favorable for Rhassoul clay. Hence, Rhassoul clay exhibits much higher adsorption capacity than Red clay. The both clays studied could be potentially used for the removal of cationic dye from wastewater.
Valorization of Tunisian Pottery Clay onto Basic Dyes Adsorption
International Journal of Environmental Research, 2014
This study examined the adsorption behavior of two cationic dyes used in textile industries (CIBasic Red 46 and CI Basic Blue 3) on Tunisian clay used in pottery. The ability of pottery clay to remove thebasic dyes from aqueous solution was compared to that of the commercial powdered activated carbon (PAC)and raw clay. Physicochemical characteristics of these adsorbents were performed by Boehm dosage, pHPZCand CEC determination, particle size distribution and spectroscopic analysis (FTIR and UV-Vis). The pHPZCof the pottery clay was about 9.86 and the CEC was about 15.6 meq/g. The empirical kinetic data fitted verywell the pseudo second order model for the adsorbent studied. The isotherm data fitted rightly to the Langmuirisotherm model. The maximum adsorption capacities of the raw clay, pottery clay and PAC onto CI Basic Red46 (CI Basic Blue 3) were respectively2806 mmol/g(785 mmol/g), 2114mmol/g (116.2mmol/g) and 2123mmol/g (343.9 mmol/g). These results showed the large adsorption...
Treatment of dye-containing effluent by natural clay
Journal of Cleaner Production, 2015
Treatment of dye-containing effluents is a significant challenge because dyes are toxic and pose a threat to the environment. Recent studies have shown that natural clay is able to efficiently remove colour from effluents that contain dyes and various additives. The objective of this study is to investigate the combined effects of dyes, salts and auxiliary chemicals used in the dyeing process, on the adsorption process onto natural clay for the treatment of dye-containing effluents. Batch adsorption experiments were performed using real and synthetic effluents containing dyes (Reactive Red 120, Reactive Orange 84 and Reactive Blue 160), and natural clays (Fouchana and Tabarka). The results show that both of the natural clays are efficient in treating real effluents. Fouchana clay shows a higher efficiency than Tabarka clay in the discolouration of the most colour loaded solution. The added chemical of enzymatic nature (Catalase) facilitates the adsorption of anionic dyes onto clay, likely by electrostatic attraction interaction with the SO 3 groups in the dye, followed by the adsorption onto the clays, of the dye-enzyme system. The mixture of all additives, enhances the adsorption of dyes on the clays, and does not act as a barrier to the decolouration process. Therefore, clays which are inexpensive and effective adsorbents may be promising alternatives for the treatment of the textile dyeing effluents.
Dyes adsorption using clay and modified clay: A review
Journal of Molecular Liquids, 2018
The effective use of the sorption properties of different clays as sorbents for the removal of dyes from wastewater has currently received much attention because of the eco-friendly nature of clay materials. Dyes are complex class of organic compound having wide range of applications in textile and food industries and a large amount of dyes are wasted, which get mixed in natural water resources. Mixing of dyes in water resources must be prohibited for the safety of natural ecosystem. The adsorbents (natural and modified) have been successfully for the adsorption of dyes form wastewater. This review article highlights the importance of clay (simple and modified) as an adsorbent for the adsorption of dyes from textile wastewater. Appropriate conditions for clay-dye system and adsorption capacities of a variety of clays are presented and sorption process is critically analyzed in this study. Studies reported the clays as an adsorbent from 2004-2016 are included and different properties for the utilization of clay and clay-based adsorbents are discussed for effective removal of dyes. Based on studies, it was found that the clays (natural and modified) are affective adsorbents for the purification of wastewater containing dyes.

Clays, particularly kaolinite, are promising adsorbents for the treatment of textile effluents, but there is a need of better understanding the mechanisms of adsorption, especially in the case of anionic dyes. Thus, the removal of RR120 anionic dye was investigated using Tunisian raw clay (TBK) composed of kaolinite and illite, and a standard kaolinite (KGa-2), and conducting batch experiments by varying different parameters (contact time, ionic strength, concentration, temperature). We investigated the clays' surface charges by electrophoretic mobility measures and the dye-clay interactions during adsorption, by the streaming-induced potentials (SIP). The results showed that KGa-2 has higher adsorption capacity for RR120 dye than TBK clay, moreover enhanced by increasing the ionic strength and/or lowering the pH of the aqueous. The SIP results showed an increase of negative charges for both clays, reflecting the adsorption of the anionic dye on the positive charges of the amphoteric surfaces of the clays. The SIP magnitudes indicated a higher adsorption rate for KGa-2 in accordance with the kinetic study. The Sips model that described the best adsorption isotherms indicates lateral interactions of the dye molecules, stronger in the case of KGa-2 than TBK. Also, the dye molecules form a thinner layer on KGa-2 surfaces. In addition, the dye molecule's structure was not altered, as verified by mass spectrometry. The adsorption process was feasible and spontaneous and favored at ambient temperature. Thus, kaolinite-rich clays are effective in the removal of anionic dyes in aqueous solution and potential good adsorbents in wastewater treatment.
Local Algerian clay characterization for toxic dyes removal
2020
Chemical industry growth has a crucial role in socioeconomic development. However, colossal amounts of toxic effluents are created as a result of manufacturing activity. Dyes, extensively used as a coloring agents in wide range of industrial activities in particular textiles, contributes significantly to wastewater discharges. More than 7 × 10 5 tons of synthetic dyes are produced annually across the world and 10-15% are wasted throughout dyeing process. Long-stand of those pollutants in water causes environmental pollution and damage aquatic life. Therefore, finding a reliable and practical solutions to mitigate these harmful hazards becomes a necessicity.
Water Resources and Industry, 2015
Inexpensive and easily available Moroccan natural clays were investigated for the removal availability of textile dyes from aqueous solution. For this purpose, the adsorption of methylene blue (MB) as reference molecule, malachite green (MG) representative of cationic dyes and methyl orange (MO) representative of anionic dyes, was studied in batch mode under various parameters. The clays were characterized by means of XRD, cationic exchange capacity and BET surface area analysis. The experimental results show that, the adsorption was pH dependent with a high adsorption capacity of MB and MG in basic range and high adsorption of MO in acidic range. The pseudo-second-order kinetic model provided the best fit to the experimental data for the adsorption of MB and MG by the clays. However, the adsorption of MO was more suitable to be controlled by an intra-particle diffusion mechanism. The equilibrium adsorption data were analyzed by Langmuir, Freundlich and Dubinin-Radushkevich isotherm models. The adsorption process was found to be exothermic in nature in the case of MB and MO. However, the adsorption of MG was endothermic.

Removal of Basic Dyes from Aqueous Solutions by Adsorption onto Moroccan Clay (Fez City)
Mediterranean Journal of Chemistry, 2019
The main objective of this study was to investigate the potential of natural clay obtained from Fez city, Morocco) as an adsorbent for the removal of basic dyes (Astrazon Blue BG and Astrazon Yellow 7GLL) from liquid effluents. Natural clay was characterised using different physical-chemical methods, including nitrogen adsorption-desorption isotherms, X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), pH of the point of zero charge (pH PZC) and Boehm titration method. The clay was tested to remove various textile dyes from the aqueous solution at room temperature. Parameters such as initial dye concentration, solution pH, adsorbent dosages and contact time were performed in a batch system for controlling the operating conditions. Experimental results indicated that the adsorption process is a fast and spontaneous reaction. A pseudo-second-order kinetic model provides the best fit to the experimental data of BG and YL adsorption onto the natural clay. The adsorption isotherm data of both the dyes onto the natural clay were fitted well to the Langmuir model. A maximum monolayer adsorption capacity of 101 mg.g-1 for BG and 127 mg.g-1 for YL are obtained at 298.15 K. The results suggest that the natural clay could be used as an inexpensive adsorbent for the removal of the textile dyes from aqueous solutions.

The treatment of textile effluents is still a great challenge and constant research is done to find sustainable efficient processes. Natural clays are promising adsorbents for removal of pollutants, particularly dyes from effluents. But there is a need of better understanding the mechanisms of adsorption, especially in the case of anionic dyes. In this study, we investigated the adsorption capacities for RR120 anionic dye, of raw clays such as Tabarka (kaolinite and illite), Fouchana (smectite, kaolinite and illite), a standard kaolinite (KGa-2), and a standard palygorskite (PFl-1). Batch experiments were performed by varying different parameters. Electrophoretic mobility and streaming induced potentials (SIP) measures were done to investigate the clays surface charges and the dye-clay interactions during adsorption. The results showed that although palygorskite exhibits the highest porosity and specific surface, its capacity to adsorb RR120 is the lowest compared to the other clays...

The aim of the present work is to explore and compare the adsorption capacity of two different clays for removal of textile dye from aqueous solutions. For this purpose, the adsorption of Green Remazole 6B; a reactive dye used in textile industry, was studied in batch mode. The clays used were provided from two different deposits in west of Algeria, one located in Ain-Temouchent (C46) and the other in the region of El Bayadh (C32). Before investigating the adsorption of textile dye, the clays were characterized by various techniques of analysis in order to study all the relevant features. The techniques used are: X-ray diffraction, infrared spectroscopy (IR) and Chemical analysis. Chemical analysis and infrared spectroscopy (IR) show that clays are mainly constituted of alumina and silica in major quantities and other elements in minor quantities. XRD analysis shows that C46 is illite clay, contaning kaolinite, smectite and quartz. On the other hand, C32 is kaolinite clay with prese...
A STUDY OF THE REMOVE CATIONIC AND ANIONIC DYES IN AQUEOUS SOLUTION BY A NEW NATURAL CLAY
The objective of this work is to study the possibility of eliminating both dyes Methylene Blue (MB) and Congo Red (CR) by adsorption on natural clay of the region of Agadir and determine the different reaction parameters effect on the proceeds. Orientation tests have been carried out in distilled water solutions. The results of the kinetics of adsorption showed that optimal contact time is 60 min; it corresponds to a maximum removal rate of MB and CR respectively of the order of 99% and 75%. Increased adsorbent ratio (0,1 à 2 g / l) improves the removal efficiency of the CR especially dyes for an initial concentration of 10 mg/l. NaNO3 salt and pH of the medium greatly influence the CR of retention. Whatever the reaction parameter tested; it appears that the clay has a good efficiency for the retention of two dyes.
Adsorption of textile dyes on raw Tunisian clay: Equilibrium, kinetics and thermodynamics
Journal of Advances in Chemistry, 2015
Natural clay from Nabeul region (north of Tunisia) was investigated for the removal of two anionic textile dyes (RR120 and BB150) from aqueous solution. The raw clay was characterized by means of XRD, IR spectroscopic, chemical analysis, cation exchange capacity and BET surface area analysis. Adsorption studies were carried out under various parameters such as pH, contact time, initial dye concentration and temperature. The adsorption kinetic data was tested by pseudo-first order, pseudo second-order and intra-particle diffusion kinetic models. The equilibrium data were analyzed using Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherm models. The thermodynamic parameters (H°, S° and G°) of the adsorption were also evaluated. The adsorption process was found spontaneous and endothermic in nature. The kinetics of adsorption were best described by pseudo-second order kinetic model. The Langmuir adsorption model totally agrees with the experimental data.
Adsorption of Basic Dyes onto Natural Clay
Adsorption Science & Technology, 2004
The adsorption ability of natural clay towards the removal of basic dyes from aqueous textile solutions was investigated. The equilibrium isotherms were measured and analyzed using the Langmuir model and the experimental results compared with the theoretical data. The adsorbent exhibited considerable adsorption capacities of 567, 526, 427 and 300 mg/g towards Neutral Red, Methyl Violet, Methyl Green and Methylene Blue, respectively. Thus, the clay may be used as a cost-effective industrial adsorbent for the removal of basic dyes from industrial effluents.
Adsorption of dyes using different types of clay: a review
Applied Water Science, 2015
Increasing amount of dyes in the ecosystem particularly in wastewater has propelled the search for more efficient low-cost adsorbents. The effective use of the sorption properties (high surface area and surface chemistry, lack of toxicity and potential for ion exchange) of different clays as adsorbents for the removal of different type of dyes (basic, acidic, reactive) from water and wastewater as potential alternatives to activated carbons has recently received widespread attention because of the environmental-friendly nature of clay materials. Insights into the efficiencies of raw and modified/activated clay adsorbents and ways of improving their efficiencies to obtain better results are discussed. Acid-modified clay resulted in higher rate of dye adsorption and an increased surface area and porosity (49.05 mm 2 and 53.4 %). Base-modified clay has lower adsorption capacities, while ZnCl 2 -modified clay had the least rate of adsorption with a surface area of 44.3 mm 2 and porosity of 43.4 %. This review also explores the grey areas of the adsorption properties of the raw clays and the improved performance of activated/modified clay materials with particular reference to the effects of pH, temperature, initial dye concentration and adsorbent dosage on the adsorption capacities of the clays. Various challenges encountered in using clay materials are highlighted and a number of future prospects for the adsorbents are proposed.
Clean-up of wastes from the textile industry using anionic clays
Clays and Clay Minerals, 2011
Toxic dyes must be removed from waste water coming from the textile and paint industries. Adsorption is one possible method of removing dyes under 'soft' conditions, without the generation of secondary hazardous materials. The present study used the carbonate-containing layered double hydroxides (LDH), Mg-Al and Mg-Zn-Al (with a M 2+ /M 3+ ratio of 3), as adsorbents to remove two industrial colorants, Astrazon Remazol Brilliant Blue and Direct Red, present in low concentrations in aqueous solutions. The physicochemical properties of adsorbents at the surfaces of LDH, as well as the properties of the solutions containing the dyes control how the colorants are removed. Both fresh and calcined LDH were effective in the removal experiments, with effectiveness ranging from 50 to 100%. Analysis of kinetic data demonstrated that the adsorption process fitted the pseudo-second-order model better than the pseudo-first order model, information which is useful for system design in the treatment of wastes from the textile industry. Parameters such as pH of solutions and concentration of dye in solution influenced mainly the initial adsorption rate.
Removal of textile dyes from waste water of Kiffry textile factory using natural clay of the area
The pollutant from dyeing industries is highly toxic. The removal of dyes from wastewater before its discharge is a necessary practice for water industry. Clay samples of two different locations of Kiffry region were selected as natural clay minerals (Red clay and Yellow clay) and China clay was taken as a reference. Chemical composition of the clay samples were analyzed using XRF technique. The specific surface area (SSA) was found to be116 and 83.77 m 2 .g -1 for Brown clay and yellow clays respectively. Adsorption and removal of a commercial textile dye from aqueous solutions at 25oC on the clays has been studied. The equilibrium time of the adsorption were achieved after 35min. The adsorption capacities of the adsorption of the textile dye onto the clays were determined. Brown clay showed the best adsorptive capacity with Qmax of 1.2 mg.g -1 followed by Yellow clay with Qmax 0.65 mg.g-1 and then China clay with Qmax of 0.34 mg.g -1 for adsorption of textile dye. While there are ...
