“…Thus, there is a current demand to maintain the standard permissible limit of such elements in industrial effluents before discharge to the environment. Hence, a fair number of physical, chemical, and biological methods have been employed to embark upon the problem of the removal of these materials from wastewater [2][3][4][5][6][7][8]. Compared to many expensive techniques, adsorption is preferred due to its flexibility, compatibility, low cost, and regeneration ability [9][10][11].…”

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.

“…Recently, bio-based composites have been subject to increased interest due to their non-toxic properties, biodegradability and surface reactivity. Very few works have demonstrated the developed biocomposites with modified kaolinite-rich clay using chitosan and cellulose nanocrystals, evaluating their adsorption capacity by studying adsorption for chromium(VI) and methylene blue solution [ 25 , 26 , 27 ].…”

The influence of star-shaped (PAA-SS) and linear polyacrylic acid (PAA) with different molecular weights (high—PAA-HMW and low—PAA-LMW) on the structure of the adsorption layer, adsorption amount, electrokinetic and stabilizing properties of the PAA/CTAB/nanoclay suspensions was studied. The properties of the systems containing one of these polymers, the cationic surfactant—hexadecyltrimethylammonium bromide (CTAB) and the surface-modified nanoclay (N-SM) were analyzed using the following techniques: BET, CHN, FT-IR, ED-XRF, XRD, HRTEM, UV-Vis, tensiometry and zeta potential measurements. It was proved that PAA could be used as an effective stabilizer of N-SM. Moreover, the addition of CTAB caused a significant increase in the stability of the systems but decreased the adsorption of PAA on the N-SM surface and changed the structure of the adsorption layers. The largest stability was observed in the PAA-HMW/CTAB system. The PAA polymers and PAA/CTAB complexes adsorbed, especially on the clay surface, influenced the primary distribution of the layered sheets but kept the same basal d-spacing. The adsorption of PAA and the PAA/CTAB complexes took place mainly at the plate edges and on the contact space between the sheets. The obtained results will be used for the preparation of the PAA/CTAB/nanoclay composite for water purification.

In recent decades, increased domestic and industrial activities have led to the release of various pollutants into the aquatic environment. A robust and eco-friendly technique for removing these pollutants from wastewater is a crucial need. Among existing technologies, adsorption is considered to be a simple, cost-effective, and sustainable method. Recently, chitosan−clay nanocomposites have emerged because of their high abundance, ease of fabrication, and efficacy as adsorbents. Quantitatively, this particular class of composites is capable of removing ∼99% of dyes, metals, and harmful negative ions from various solutions. Also, the composite is designed to remove a maximum of ∼94% of the targeted herbicides from media under investigation. This review summarizes important information about this adsorbent in removing micropollutants from various water sources. A short overview of the chemical structure and the modification of chitosan and clay, along with their interaction within the composite matrix and with contaminants, is presented. Finally, a critical analysis of the removal performance of these composites compared with that of other industrial adsorbents is provided. Future research directions are suggested on the basis of the technological challenges faced in the industrial implementation of these materials.
