Preparation and Characterization of a Novel Chemically Crosslinked Chitosane-g-Polyacrylamide Hydrogel as a Promising Adsorbent for the Removal of Methylene Blue from Aqueous Solutions

Chitosan- or glycidyl methacrylate-based adsorbents for the removal of dyes from aqueous solutions: a review

“…The adsorption percentages were 70-90% after five cycles of adsorption. 60 Sehil et al 61 developed a new 3D CS-g-polyacrylamide (CS-g-PAA) hydrogel through radical polymerization using sodium trimetaphosphate (TMP) as a crosslinking agent. Structural confirmation of the synthesized hydrogel was carried out using FT-IR and X-ray diffraction analysis.…”

“…According to thermodynamic studies, it was revealed that the adsorption of MB onto the hydrogel was a spontaneous and exothermic process. 61…”
