Synthesis of a hydrogel by grafting of acrylamide-co-sodium methacrylate onto chitosan for effective adsorption of Fuchsin basic dye.

This work was designed to produce effective adsorbent from acrylamide (AAm), sodium methacrylate (SMA), and chitosan (CTS) through free radical grafting polymerization for removing the Fuchsin dye from its solution. The gel fraction and the grafting parameters were studied, and the results showed maximum grafting percentage (1014.3%) and gel fraction (83.
