N2 - Abstract: New modified epichlorohydrin chitosan Schiff base (ECS-MC) was successfully synthesized and characterized by various techniques such as FT-IR, TGA, DSC, BET, XRD and SEM. In addition, methyl green (MG) removal efficiency from aqueous solution has been studied and the influence of solution pH, sorbent dose, initial MG concentration and contact time were investigated. The results of adsorption study indicated that 99.12% of MG dye were removed via adsorption using 0.02 g of ECS-MC at pH of 8 and 120 min solution shaking. Results showed high MG sorption capacity of 194.4 mg/g, when 0.005 g of ECS-MC was used as sorbent. Then, ECS-MC can be more efficient for removal of other cationic dyes. Graphic Abstract: The mechanism of MG adsorption on the surface of ECS-MC depends on functional groups of both adsorbent and adsorbate. It was clear that the electrostatic interaction such as π–π and H-bonds between the sorbent and methyl green played a main role in MG adsorption. [Figure not available: see fulltext.]
