“…Figure 1 shows the FTIR spectra of Cs, CsT and CsTC1 and CsTC2 composites. (amide stretching), 1533 cm -1 (-N-H bending), 1426 cm -1 (-C-H symmetrical deformation), and 1063 cm -1 (C-O-C stretching of saccharide structure of chitosan) [11,38].

“…Because the amine groups of Cs can acquire a net positive charge when protonated, Cs has a high efficiency towards adsorption of anionic dyes over cationic dyes. With the progress in the science and technology, advanced techniques have been appeared to enhance the adsorption performance of Cs towards cationic dyes [11][12][13]. From these technique is compounding Cs with other organic and/or inorganic materials that have affinity towards cationic dyes such as graphene oxide, manganese dioxide, polyaniline, sodium alginate, clay, magnetic nanoparticles, silica , carbon materials, cellulose and karaya gum [8,11,[14][15][16][17][18][19][20] .…”

Due to the wide variety of synthetic dyes present in wastewater, there has been an urgent need to develop adsorbent materials to remove both cationic and anionic dyes. Since the development of such materials is still challenge, this paper is an attempt to prepare an economic and eco-friendly adsorbent material from chitosan to remove both cationic and anionic dyes from aqueous solution. Hence, hybrid composites from chitosan (Cs), talc powder (T) and cloisite 30B (C) with different weight ratios of 1: 2: 0, 1: 2: 1 and 1: 2: 2 were prepared. Chemical structure, thermal stability and surface morphology of the prepared composites were studied by using FTIR, TGA and SEM. The affinity of the prepared composites towards adsorption of cationic crystal violet (CV) and anionic reactive yellow 145 (RY) dyes was investigated. The adsorption results showed that the composite with a weight ratio of 1: 2: 1 is the most effective adsorbent for removal of RY dye with 76.9 mg/g adsorption capacity, whereas the composite with a weight ratio of 1: 2: 2 exhibited the highest adsorption activity for CV dye (37.03 mg/g). The adsorption of RY and CV on these composites followed the pseudo second order model. The langmuir isotherm model described the experimental adsorption data better than the Freundlich, Dubinin–Radushkevich, and Temkin isotherm models, indicating a monolayer sorption process for both dyes.

“…Cs has a high effectiveness for anionic dye adsorption over cationic dyes because of its cationic nature. With progress in science and technology, innovative strategies for improving Cs adsorption performance towards cationic dyes have emerged [13][14][15]. Additionally, pH sensitivity and swelling susceptibility limit the practical use of pure chitosan.…”

“…Additionally, pH sensitivity and swelling susceptibility limit the practical use of pure chitosan. In order to resolve these problems, Cs was modified with other organic and/or inorganic materials that have affinity for cationic dyes such as graphene oxide, manganese dioxide, sodium alginate, clay, magnetic nanoparticles, silica, carbon materials, cellulose, and karaya gum [10,13,[16][17][18][19][20][21][22]. Furthermore, these materials provide Cs with good thermal and chemical stability [10,23].…”

Designing adsorbent materials that can effectively remove many types of organic dyes is crucial because of the wide diversity of synthetic dyes found in wastewater. Thus, this study presents the synthesis of economic and eco-friendly adsorbent composites composed of chitosan (Cs), talc (T), and Cloisite 30B clay (C) to remove both cationic crystal violet (CV) and anionic reactive yellow 145 (RY) dyes for the first time. Cs was functionalized with T and subsequently the CsTC1 and CsTC2 composites were prepared by sensitizing the obtained CsT with different weight ratios of Cloisite 30B (C). X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), N2 adsorption–desorption isotherm, and zeta potential analysis were employed to characterize the materials. The addition of T to Cs matrix improves the thermal stability, pore size, and pore volume with respect to pure Cs. The effect of C inclusion was examined by measuring the affinity of the prepared composites towards adsorption of cationic CV and anionic RY dyes in comparison to pure Cs and CsT composite. The adsorption results in a single dye solution revealed that the CsTC1 composite is the most effective adsorbent for removal of RY dye with 76.9 mg/g adsorption capacity, whereas the CsTC2 composite exhibited the highest adsorption activity for CV dye (37.03 mg/g). Furthermore, RY and CV co-adsorption on CsTC composites was tested from a mixed dye solution. The adsorption kinetics of RY and CV adsorption followed the pseudo second order model. Langmuir isotherm model described the experimental adsorption data better than the Freundlich, Dubinin–Radushkevich, and Temkin isotherm models, indicating a monolayer sorption process for both dyes. The proposed mechanism for RY and CV adsorption using CsTC composites was investigated.
