The main aim of this work is to treat sugarcane bagasse agricultural waste and prepare an efficient, promising, and eco-friendly adsorbent material. Biochar is an example of such a material, and it is an extremely versatile and eco-friendly biosorbent to treat wastewater. Crystal violet (CV)-dye and methylene blue (MB)-dye species are examples of serious organic pollutants. Herein, biochar was prepared firstly from sugarcane bagasse (SCB), and then a biochar biosorbent was synthesized through pyrolysis and surface activation with NaOH. SEM, TEM, FTIR, Raman, surface area, XRD, and EDX were used to characterize the investigated materials. The reuse of such waste materials is considered eco-friendly in nature. After that, the adsorption of MB and CV-species from synthetically prepared wastewater using treated biochar was investigated under various conditions. To demonstrate the study’s effectiveness, it was attempted to achieve optimum effectiveness at an optimum level by working with...

Wastewater discharged from the textile industry poses significant environmental and societal challenges due to the presence of hazardous dye pollutants. This study explores a novel approach for the removal of methylene blue, a common textil e dye, from water using adsorbents derived from orange peels. The goal is to mitigate water pollution, thereby reducing harm to ecosystems and living organisms, while simultaneously addressing the issue of environmental litter generated by discarded orange peels. In this study, the removal of methylene blue dye from textile wastewater using adsorbents made from orange peels was examined. Orange peels were collected, washed, dried, charred at 500 °C, ground into powder, and activated with phosphoric acid to create an activated carbon with a bulk density of 0.987 g/mL, 15% moisture, 3% ash content, and a surface area of 52.5 m²/g. It was found that adsorption rates increased over time, reaching equilibrium after 120 minutes, with a maximum removal efficiency of 90% achieved using 0.6 g of adsorbent. The study concluded that orange peel-derived adsorbents could be an effective and ecofriendly method for reducing water pollution and repurposing agricultural waste, presenting a viable solution to the environmental challenges posed by the textile industry.
Adsorption of Brilliant Green Dye on Biochar Prepared From Lignocellulosic Bioethanol Plant Waste
Clean soil air and water, 2015
This study was aimed at the adsorption of Brilliant Green (BG) on hydrolyzed rice straw biochar, which was obtained from a lignocellulosic bioethanol process. Rice straw biochar (RBC) possessed surface properties such as a Brunauer-Emmett-Teller (BET) surface area of 232.31 m 2 /g, a total pore volume of 0.30 cm 3 /g, and an average pore width of 5.22 nm. Adsorption studies were carried out to investigate the effect of experimental factors such as pH (2-10), biochar dose (0.05-1.25 g/L), contact time (30-480 min), and temperature (30 to À50°C) on the adsorption of BG. The Langmuir isotherm (R 2 ¼ 0.998) fitted well to the adsorption data for initial dye concentrations of 20-500 mg/L, implying that BG adsorption occurred in the form of a monolayer on RBC. Adsorption kinetics was well fitted by the pseudo-second order kinetic model (R 2 ! 0.988) for all tested dye concentrations. The thermodynamic study revealed that BG adsorption on RBC was spontaneous, favorable, and a physical process. The maximum adsorption capacity of RBC was found to be 111.11 mg/g. These results showed that RBC, prepared from the waste of the bioethanol process, can be effectively used as a promising cheap adsorbent to remove dyes from aqueous solution. This approach of product diversification (bioethanol along with biochar) may lead to a cost effective and cleaner production of bioethanol.

Dyeing industries, including textiles, dyestuffs, printing, leather, and plastics industries have significantly contributed to water pollution by releasing untreated wastewater tainted with dyes into our water bodies. Discharging such wastewater can severely impact both humans and the ecosystem; therefore, treatment is essential before its release. Adsorption, one of the most effective methods for removing various colors from a water system, has gained significant attention due to its simplicity, ease of operation, simple designs, and cost-effectiveness. Agricultural biomass has emerged as a promising adsorbent for removing dyes from wastewater due to its advantages, such as sustainability, cost-effectiveness, accessibility, and environmental friendliness. This article examines various reports on different agricultural biomass adsorbent removal efficiency and adsorptive capacity. The challenges associated with the use of agricultural-based adsorbents and the prospects for future res...
Potential Application of Orange Peel as an Eco-friendly Adsorbent for Textile Dyeing Effluents
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.

Review on Application of Agro-Waste Biomass Biochar for Adsorption and Bioremediation Dye
BJSTR, 2017
This review brings the little knowledge about the effectiveness of combined bio-film and biochar approach in bio-sorption method for the removal of synthetic dye which generated from wastewater of textile and carpet industries. Removal studies of dye through packed bed bioreactor performed with immobilized bacteria on agro waste biomass and biochar (i.e., biofilms on biochar). This review suggests the combined approach may be a likely factor of treatment of dye effluents. Several models including Langmuir isotherm and Freundlich are useful to studies of sorption of dye on to biochar prepared by agro waste.
Strategies for the sustainable management of orange peel waste through anaerobic digestion
Journal of Environmental Management, 2018
The processing of oranges is a major industry worldwide and leads to the production of large amounts of orange peel waste (OPW). Energy production through anaerobic digestion of OPW is a promising option; however, the high content of essential oil, mainly composed of D-limonene, a well-known antioxidant, can cause the inhibition of the biological activity. In this paper, different pretreatment methods were tested (e.g. ensiling, aeration, thermal and alkaline treatments) to optimize the anaerobic digestion of OPW focusing on D-limonene removal. The raw and pretreated substrates were characterized and their biochemical methane production was measured. The results demonstrated the ability of some of the treatments to reduce D-limonene content up to 80%. A relatively high biomethane potential production of OPW (up to about 500 NmL CH 4 g À1 VS) was measured. The importance of the acclimation of inoculum and the risk connected to the accumulation of inhibiting substances in the reactor is discussed.
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.

Two biochars derived from wattle bark (BA) and coffee husks (BC) used to remove methylene blue (MB) which achieved the yield values of 33.3 % to 35.08% at 500 o C of pyrolysis. Adsorption increased with the rising of the dose until 2 g/L for BC, and 5 g/L for BA, respectively. When rising pH, the increasing trend was observed for BA, and BC, from 67 % at pH of 2 to 93% at pH of 12. The equilibrium time depended on the initial MB concentration and the MB removal accounted for over 83% at the first 30 minutes. The experiment data fits better with Avrami, and Elovich than Pseudo-first-order equation (PSO), and Pseudo-second-order model (PFO). Adsorption process comprised more than one reaction pathway including integer-kinetic order, and multiple kinetic orders or fractionary kinetic order.
