The problem of the treatment of contaminated wastewaters is of the upmost worldwide interest. This contamination occurs via the presence of inorganic or organic contaminants of different nature in relation with the industry they come from. In the case of organic dyes, their environmental impact, and thus, their toxicity come from the air (releasing of dust and particulate matter), solid (scrap of textile fabrics, sludges), though the great pollution, caused from dyes, comes from the discharge of untreated effluents into waters, contributing to increase the level of BOD and COD in these liquid streams; this discharge is normally accompanied by water coloration, which low the water quality, and caused a secondary issue in the wastewater treatment. Among separation technologies, adsorption processing is one of the most popular, due to its versatility, easiness of work, and possibility of scaling-up in the eve of the treatment of large wastewater volumes. Within a miriade of potential adsorbents for the removal of organic dyes, this work presented the most recent advances in the topic.

“…High e ciency photocatalysts have been extensively studied due to their potential applications in the decomposition of toxic compounds as well as the rapid progress of modern industry (Sulaiman et al, 2016;Abboud et al, 2020). Besides, heavy metals and dyes are the most toxic e uents present in industrial wastewater, even at low concentrations.…”

The spinel zinc ferrite/alkali cellulose composite has been successfully fabricated as a magnetic photocatalyst and assessed for its photocatalytic activity toward the degradation of methylene blue (MB) in an aqueous solution. The Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX), thermogravimetric analysis (TGA), BET, and zeta potential were used to evaluate the magnetic photocatalyst composite and investigate its adsorption mechanism. Furthermore, the adsorption behavior of the composite was studied under various conditions. The ZnFe2O4/alkali cellulose composite effectively degraded (100%) MB after 180 min at a pH of 6.5 compared to cellulose, alkali cellulose and ZnFe2O4. The regeneration of the loaded composite was studied using the alcohol/water solution and reused upon a certain variation in the efficiency after the fourth cycle. The adsorption process was found to be consistent with the pseudo-second-order kinetic model.
