Research Journal of Textile and Apparel, 2013
The use of low-cost and eco-friendly adsorbents has been investigated as ideal alternatives to the current expensive methods for removing dyes from waste water. Orange peel (OP) was used as a low cost natural waste adsorbent for the removal of textile effluents. The effectiveness of (OP) in adsorbing ;C.I. Direct Red 79 (DR 79) and C.I. Direct Yellow 27 (DY 27) from their dye baths has been studied as a function of pH, solid/liquid ratio, agitation time and initial dye concentration. The sorption isotherms were analyzed using Langmuir and Frendlich models. The results indicated that acidic solutions supported the adsorption of the studied dyes within (OP). Adsorption kinetic models were analyzed using the pseudo-first, second order equation and intraparticle diffusion equation. The results showed that the order equation fitted the experimental data very well. By the way, the effect of adsorbent surface was analyzed by scanning electron microscope (SEM), whereas the SEM images showed reasonable agreement with adsorption measurements.

— Environmental care is an increasing concern in our society, and therefore integrated, circular economy allowing to close the industrial cycle is an urging demand. This project employs a residue of the food industry to recover the wastewaters from the textile industry, allowing closing the loop in two different industrial processes. Orange peel is a very abundant residue in the food industry. By chemical modification of the orange peel, we aim to produce a biosorbent to be employed in the treatment of the textile industry wastewater containing cationic dyes. In this project, we evaluate the capacity of the treated orange peels as cationic interchanger with different dissolutions of copper (II). Finally, their capacities as biosorbents were evaluated with four cationic dyes, examining the influence of different parameters like: biosorbent concentration, contact time, temperature and pH of the medium. An adsorption between 51 and 92 % was reached with the first treatment and also the possibility of the biosorbent recovery.
Removal of dyes from textile effluent using fruits and vegetable peels as efficient biosorbents
Journal of emerging technologies and innovative research, 2020
Color removal from effluents polluted with dyes of textile industries has been considered a challenge due to the difficulty faced in treating such wastewaters. Natural materials such as polysaccharides have gained attention due to their peculiar properties such as being biocompatible, biodegradable, renewable and non-toxic. Due to these properties they are used as efficient bio sorbents. In this study carbonized bio peels of fruits and vegetable were used as simple adsorbents for removal of dyes. These materials were also evaluated for different pH, dye concentration, particle size and contact time of adsorbent for the removal of dyes from wastewater. Experiment results have shown that on decreasing the concentration of dyes along with increase in contact time the dye removal from bio char was more effective. The study is the preliminary effort for use of carbonized bio peel for removal of colorants in effluent waters. Keywords—dyes, bio peels, carbonization, adsorption.
Dye Removal from Textile Wastewater using Bioadsorbent
Textile industries throughout the world produce huge quantities of dyes and pigments are produced annually throughout the world, especially by textile industries. Effluents from textile industries are dye wastewater and the disposal of these wastes to receiving freshwater bodies causes damage to the environment. Among the treatment technologies, adsorption is an attractive and viable option, provided that the sorbent is inexpensive and readily available for use. In this study, a typical basic dye, methylene blue, in wastewater was treated using Melia azedarach sawdust. The effects of contact time, adsorbent amount and particle size were investigated on the removal efficiency of adsorbent for methylene blue. Complete removal of the dye were attained at higher adsorbent dose of 3 g/L with 50 mg/L initial dye concentration. The maximum adsorption was at 240 minutes, whereas more than 90% removal with 105 µm particle size of 1g/L adsorbent for same initial dye concentration. The experim...
Removal of Dye from Wastewater Using Agricultural Waste as Low Cost Adsorbent
2020
Dyes are widely used in industries such as textiles, rubber, plastics, printing, leather, cosmetics, to colour their products. As a result, they generate a considerable amount of coloured wastewater. Colour removal from textile effluents on a continuous industrial scale has been given much attention in the last few years, not only because of its potential toxicity, but also mainly due to its visibility problem. Discharge of dye from wastewater into natural streams and rivers poses severe problems to the aquatic life, food chain and causes damage to the nature of the environment. Dyes absorb and reflect sunlight entering water and so can interfere with the growth of bacteria and affects photosynthesis in aquatic plants. The problems become greater due to the fact that the complex structures of the dyes remain ineffective in the presence of heat, light, microbes and even oxidizing agents that affects degradation of the dyes. Hence, these pose a serious threat to human health and water...
Removal of Colour (dyes) from textile effluent by adsorption using Orange and Banana peel
In the present paper natural adsorbent banana and orange peel was used for removal of colour from waste effluent of textile industry. The materials were obtained and treated for the removal of colour at different doses. These materials also evaluated for the removal of colour at different pH and time. The materials are capable of removing colour from waste water, their colour removal capacity for banana peel is 87% and orange peel is 68 % respectively at normal pH and temperature conditions. The equilibrium time was found 55min for orange peel and 45min for banana peel. The experimental adsorption data fitted with Langmuir and Freundlich adsorption isotherms. The experimental result shows that the materials have good potential to remove colour from effluent and good potential as an alternate low cost adsorbent.
Adsorption of dyes from aqueous solution under batch mode using cellulosic orange peel waste
DESALINATION AND WATER TREATMENT, 2018
The present work aimed at studying the use of orange peel (OP) biosorption for the removal of methylene blue (MB) and Congo red (CR) from aqueous solution. The influences of initial dye concentration and contact time on the biosorption process were studied. Experimental data were modeled by Langmuir and Freundlich isotherms. The former fitted better the equilibrium data for both dyes. The monolayer biosorption capacity of OP was 256.4 and 102.0 mg/g for MB and CR, respectively. The calculated thermodynamic parameters, namely ∆G, ∆H and ∆S showed that the biosorption of the two dyes was spontaneous and exothermic under the examined conditions. Experimental data were also analyzed using biosorption kinetic models. The results showed that the biosorption processes of dyes on OP obey pseudo-second-order kinetics. Our results prove that an agriculture waste (i.e. OP) can be used to eliminate dyes from aquatic solution efficiently.
REVIEW PAPER ON REMOVAL OF A DYE FROM AQUEOUS SOLUTION BY ADSORPTION
To investigate the adsorption capacities of locally available low cost bio-adsorbents like neem leaves, orange peels, peanut hulls and coconut coir pith powders to remove colour in a textile industry wastewater, experiments were performed. The experiments were conducted at pH of 7 with different process parameters like adsorbent dosage, temperature, contact time and agitator speed using batch adsorption method. From the experimental results, the maximum colour from the textile industry wastewater was obtained at an optimum adsorbent dosage of 350 mg, an optimum contact time of 73 min., an optimum temperature of 330 K and an optimum agitator speed of 650 rpm. Further, from the validation experiments, it was found that the maximum colour removal percentage in textile industry wastewater is about 75.2%, 78.3%, 86.6% and 81.7 % respectively for neem leaves, orange peels, peanut hulls and coconut coir pith powders. This result was higher than the results obtained by different process parameters for various bio-adsorbents. Finally, from the results of adsorption study, it was concluded that bio-adsorbents used as a coagulant for removing the colour from textile industry wastewater especially peanut hulls powder because of its higher adsorptive capacity than other bio-adsorbents used in this study.

Purpose This study aims to demonstrate that orange-derived and lemon-derived systems can be used in continuous processes as efficient adsorbents to the entrapment of some anionic and cationic dyes in the textile dyeing wastewater effluents. Design/methodology/approach Physically and chemically modified orange and lemon mesocarps are used as natural adsorbents for the cationic dyes Basic Blue 3, Basic Yellow 21, Basic Red 18 and Basic Green 4 and the anionic dyes Acid Blue 264, Acid Yellow 49 and Acid Red 337, all commonly used in the textile dyeing industry. Adsorption capacities of the orange-derived and lemon-derived adsorbents on the dyes are studied simulating a batch and continuous industrial processes. Findings Results demonstrate that treated orange mesocarp (orange-derived adsorbent) can adsorb up to 97% of cationic Basic Green 4 in 30 min, whereas the lemon mesocarp (lemon-derived adsorbent) can retain up to 88% within the same time. In the case of anionic, 91% Acid Blue 26...
