“…Chitosan, obtained from chitin, is a relatively inexpensive material as chitin is the second most abundant polymer in nature next to cellulose [14,15]. It has shown many potential applications in the fields of wastewater treatment [14,16,17], tissue engineering [18], agriculture [19,20], biomedicine [21], drug delivery [22], and so on. Chitosan can be extracted from the exoskeletons of crustacean fungi and some insects.…”

In recent years, there has been increasing interest in developing green biocomposite for industrial wastewater treatment. In this study, prawn-shell-derived chitosan (CHT) and kaolinite rich modified clay (MC) were used to fabricate biocomposite beads with different compositions. Prepared composite beads were characterized by FTIR, and XRD, and SEM. The possible application of the beads was evaluated primarily by measuring the adsorption efficiency in standard models of lead (II) and methylene blue (MB) dye solution, and the results show a promising removal efficiency. In addition, the composites were used to remove Cr (VI), Pb (II), and MB from real industrial effluents. From tannery effluent, 50.90% of chromium and 39.50% of lead ions were removed by composites rich in chitosan and 31.50% of MB was removed from textile effluent by a composite rich in clay. Moreover, the composite beads were found to be activated in both acidic and basic media depending on their composition, which gives a scope to their universal application in dye and heavy metal removal from wastewater from various industries.

“…About half of the global synthetic dyes are classified as nonbiodegradable and carcinogenic. − During dyeing, a significant portion (30–50%) of dye gets unfixed and thereby is retained in water and needs to be treated. ,, The basic principles of wastewater treatment include separation of suspended and dissolved solids, oxidation of oxygen demanding components, neutralization, and removal of toxic substances as well as removal of unfixed dyes . For TW treatment, various methods such as physical, chemical, and biological process are applied efficiently. ,, Nowadays, adsorption process, a physical method, is regarded as the most effective way for the treatment of TW; − however, disposal, management, and regeneration of the adsorbents accompanied by sludge after the adsorption pose another environmental headache. Also, following these processes, it is hardly possible to recover dyes after removing from wastewater and reusing them further. − …”

Dye containing industrial effluent streams are a cause of major environmental concerns, especially those which are not easily biodegradable. Many techniques have been developed to remove dyes from the waste stream; however, most of them suffer from a weakness of efficiency and effectiveness when an attempt is made for industrial implementation. A recently developed dye removal method using surfactants offers the benefits of high removal efficiency, ease of waste disposal, scope of efficient recovery, and the use of nontoxic and less harmful reagents. This review aims to contribute to this growing area by summarizing the mechanisms of dye−surfactant interactions and investigating the influence of different process parameters such as pH, concentration of surfactants, dyes, and electrolytes, temperature, etc. on the efficiency of the method. The review also attempts to present future research scopes of these techniques with a critical analysis of industrial applicability.

“…Chitosan is a natural polysaccharide produced from the N -deacetylation of chitin under alkaline conditions. In addition, chitosan possesses abundant polar hydroxyl (−OH), amino (−NH 2 ) groups in its N -acetyl-glucosamine monomers that can act as a chelating agent to adsorb potentially toxic pollutants (i.e., potential toxic metal ions) …”

“…In addition, chitosan possesses abundant polar hydroxyl (−OH), amino (−NH 2 ) groups in its N-acetyl-glucosamine monomers that can act as a chelating agent to adsorb potentially toxic pollutants (i.e., potential toxic metal ions). 2 However, the mechanical weakness of chitosan-based hydrogel beads is a major challenge for its application in water and wastewater treatment. 3 Additionally, the poor chemical stability of chitosan in an acidic media (pH ≤ 3.0) restricts its wide application in the real water treatment process.…”

Chitosan-based hydrogel beads were prepared through neutralization with an alkali gelation process, whereas pristine hydrogel capsules with a core−shell membrane structure were synthesized through an anionic surfactant gelation process. The anionic surfactant (sodium dodecyl sulfate; SDS) in the capsules was completely extracted through a green exchange with an (NaOH) alkali solution. The extracted surfactant solution can be continuously reused for synthesizing hydrogel capsules. The effects of alkali treatment on the changes in the morphology, surface chemistry, and adsorption capacity of the capsules were investigated. The results indicated that the NaOH-treated capsules exhibited similar chemical compositions but dissimilar structures to the pristine hydrogel capsules. Optimal synthesis conditions of the green capsules (SN5) were obtained at 5 g/L of SDS gelation and 0.02 N NaOH. Moreover, the mechanical stability of hydrogel capsules was insignificantly changed by the alkali treatment as evidenced by their mass loss under ultrasonication. The alkali treatment process can remarkably enhance the adsorption rate and capacity of Congo red dye onto the capsules. The treated capsules (2592 mg/g) exhibited an excellent adsorption capacity compared to the pristine hydrogel capsules (563 mg/g) and beads (183 mg/g) because of the rearrangement of polymeric networks after the alkali treatment process. The alkali treatment process can significantly improve the adsorption capacity of capsules and completely remove the SDS surfactant in capsules. Therefore, NaOH-treated hydrogel capsules can serve as a biocompatible and green adsorbent with excellent adsorption capacity.
