In this article, we synthesize of a novel alginate-based superabsorbent hydrogel via graft copolymerization of 2-acrylamido-2-methylpropanesulfonic acid (AMPS) onto alginate backbones. The polymerization reaction was carried out in an aqueous medium and in the presence of ammonium persulfate (APS) as an initiator and N,N'-methylene bisacrylamide (MBA) as a crosslinker. A proposed mechanism for hydrogel formation was suggested and the structure of the product was established using FTIR and SEM spectroscopies.
