“…The achievement of dyes decolorization by adsorption with activated carbon was extensively studied. For instance, malachite green was adsorbed with curcuma-based activated carbon [65], with tetraethylenepentamine activated carbon [66] and with carbon coated layered double hydroxide [64]. Rhodamine B was successfully adsorbed by ordered mesoporous carbon and commercial activated carbon and by treated rice-husk based activated carbon Acid red 4 adsorption occurred via the activated carbon.…”

Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs of natural dye extraction engendered the discovery of synthetic dyes from petrochemical compounds. Nowadays, they are dominating the textile market, with nearly 8 × 105 tons produced per year due to their wide range of color pigments and consistent coloration. Textile industries consume huge amounts of water in the dyeing processes, making it hard to treat the enormous quantities of this hazardous wastewater. Thus, they have harmful impacts when discharged in non-treated or partially treated forms in the environment (air, soil, plants and water), causing several human diseases. In the present work we focused on synthetic dyes. We started by studying their classification which depended on the nature of the manufactured fiber (cellulose, protein and synthetic fiber dyes). Then, we mentioned the characteristics of synthetic dyes, however, we focused more on their negative impacts on the ecosystem (soil, plants, water and air) and on humans. Lastly, we discussed the applied physical, chemical and biological strategies solely or in combination for textile dye wastewater treatments. Additionally, we described the newly established nanotechnology which achieves complete discharge decontamination.

“…This process has many advantages (i) probability of adsorbent regeneration and reuse; (ii) environmentally benign; (iii) low investment cost; (iv) toxicity removal; (v) vigorous continuous and batch processes; (vi) handling micro levels of pollutants; and (vii) simple to operate and to design (Torrellas et al 2016, Bhatnagar & Anastopoulos 2017. Variety of adsorbents used for this purpose include AC (Dabek & Ozimina 2009), zeolite (Chang et al 2004a(Chang et al , 2004b, Bottom ash (Gupta et al 2012), Curcuma caesia based AC (Arora et al 2020), Chenopodium album ash (Arora et al 2019a), ash of black turmeric rhizome (Asha et al 2021), Iron based metal organic framework (Arora et al 2019b), Fe-Benzene dicarboxylic acid metal organic framework (Soni et al 2020), solid residues of agricultural activities such as pine bark and ash waste (Li et al 2010;Pérez-Gregorio et al 2010), rice husk (Hidayat et al 2019), sugar cane bagasse, green coconut shells, chitin, and chitosan (Crisafully et al 2008), as well as other organic-free hydrophilic minerals such as talc, silica and alumina (Su et al 2006;Müller et al 2007) and numerous materials such as plant derived material, sewage sludge, shells, petroleum coke and bituminous coal is used for the production of AC (Awoyemi 2011;Gupta 2015) through carbonization followed by activation processes. AC is produced depending on its particular purpose in the form of granules, powder, or briquette.…”

Serious environmental deterioration caused by synthetic waste plastics, and the pollution of freshwater resources are the most alarming and remarkable challenges of the 21st century. Therefore, immense scientific efforts are being paid towards the management of waste plastics and treatment of polluted water. The current study is report the utilization of waste polyethylene terephthalate (wPET) and waste polystyrene (wPS) for fabrication of activated carbon (AC) and its application for the removal of hazardous polycyclic aromatic hydrocarbons (PAHs) pollutants from water. AC was prepared from wPET and wPS by carbonization under N2 atmosphere followed by chemical activation with 1M KOH and 1M HCl. The AC was characterized by SEM, surface area analysis (SAA), and FT-IR spectroscopy. Adsorption of PAHs from aqueous solutions through AC was examined by batch adsorption tests. The optimum parameters for maximum adsorption of PAHs were found to be; initial PAHs concentration 40 ppm, 2 h contact time, pH 3, 5, and 7, 50 °C temperature and adsorbent dose of 0.8 g. Kinetic and isotherm models were applied to evaluate the adsorbent capacity for PAHs adsorption. The kinetic study shows that the adsorption of these PAHs onto AC follows the pseudo-second-order kinetics. The experimental results demonstrated that Langmuir isotherm model best fitted the data. The thermodynamic factors calculated such as entropy change (ΔS°), enthalpy change (ΔS°) and free energy change (ΔG°) show that the adsorption process is non-spontaneous and endothermic in nature. Results were also compared with the efficiencies of some commercial adsorbents used in practice. This examination revealed that the novel plastic derived AC possesses a large potential for elimination and recovery of PAHs elimination from industrial wastewater.

The purpose of this work was to adsorb the triphenylmethane dyes crystal violet (CV), brilliant green (BG), and malachite green (MG) from an aqueous solution using cowdung (CD) that has been gamma‐sterilized. FTIR, SEM, EDX, and TGA‐DTA advanced techniques were used to characterize CD. The material had a pHPZC of 6, and it was shown that the maximal monolayer adsorption capacities for CV (at pH 4.83), BG (at pH 4.53), and MG (at pH 3.75) were, respectively, 179.39, 172.28, and 111.62 mg g−1. The equilibrium results were completely described by the pseudo‐second order model and Langmuir isotherm. Using the van't Hoff and Arrhenius equations, thermodynamic parameters like ΔG, ΔS, and ΔH were computed. The exothermic nature of the process change is indicated by the fact that the adsorption of CV and BG increased with lowering temperature whereas the adsorption of MG increased with increasing temperature, as the process was endothermic. Curiously, the values of the adsorption capacity acquired using the column adsorption approach is very similar to those obtained using batch adsorption trials illustrating the CD's capacity for dyes adsorption.
