“…This biopolymer is found in crustaceans, especially crabs and shrimp, as well as in the cell walls of insects and fungi 25 . For some applications, chitin is converted to chitosan through deacetylation process 26 . Chitosan molecule contains a large number of modifiable functional groups, that increase its adsorption capacity 24 .…”

In this study, a novel chitosan‐based nanoadsorbent has been synthesized by the reaction between nanochitosan and epoxy‐triazinetrione. The commercial cationic dye, malachite green, was chosen as a model dye in order to inspect the adsorption efficiency of the prepared adsorbent. The kinetics and thermodynamics of the adsorption process have been explored. According to the results, the Freundlich isotherm and pseudo‐second‐order model can well elucidate the adsorption process. The obtained thermodynamic parameters indicated that the removal process was spontaneous and endothermic (ΔH° = 95.0 kJ mol−1). The effects of several parameters on the dye elimination were studied using the response surface methodology approach. A high adsorption efficiency (95%) was obtained at 29.5 min, pH 7.9, and 7.5 mg of the adsorbent. At this condition, the removal efficiency of the unmodified adsorbent was 65.4%. The novel epoxy‐triazinetrione‐modified chitosan nanosorbent was found to be highly adequate for the treatment of wastewaters containing organic dyes.

“…Methyl green is a cationic triphenylmethane dye and used for dyeing nylon, wool, silk and cotton in the textile industry [21] and as indicator dyes due to their pH sensitivity [22]. Then the pH of solution is one of the most important parameter in the adsorption process [2,411,14]. The maximum methyl green removal (353.33 mg/g) was observed in the pH of 7 for activated bentonite [23] and 67.93 mg/g in the pH of 8 for activate carbon [24].…”

“…Until now, various techniques have been reported for remove of various dyes such as biological degradation [7], oxidation [8] chemical coagulation and adsorption [1][2][3][4][9][10][11][12][13][14]. Chitosan, as a natural polymer, is harmless to humans [3], eco-friendly, nontoxic and also not expensive [2].…”

“…Chitosan, as a natural polymer, is harmless to humans [3], eco-friendly, nontoxic and also not expensive [2]. Due to containing many amine and hydroxyl groups on chitosan and its derivatives, they used as a good adsorbent for remove of various dyes [2][3][4][5][11][12][13][14]. Rahmi et al [2] reported the maximum adsorption capacity of 20.408 mg/g for the methylene blue removal using H 2 SO 4 crosslinked magnetic chitosan nanocomposite beads.…”

Epichlorohydrine crosslinked chitosan cinnamaldehyde Schiff base (Epy-Chit-cin) had been synthesized by the reaction of epichlorohydrine, chitosan and trans-cinnamaldehyde (weight ratio 1:1:1) and characterized by FT-IR, UV-Vis, TG-DTA, DSC and XRD. The efficiency of the prepared Epy-Chit-cin was studied for the methyl green (MG) dye removal from aqueous solutions. The effects of pH, adsorbent dosage and contact time on the adsorption process were evaluated. Results showed that the equilibrium of MG adsorption by Epy-Chit-cin was reached at 120 min contact time and the maximum adsorption capacity obtained 98.47 at the presence of 0.02 g of Epy-Chit-cin.
