Chitosan-graft-poly (acrylic acid) superabsorbent hydrogels by irradiation technique using Υ-rays were carried out in this work. An important application of chitosan-graft-poly (acrylic acid) is the use as water absorbent. For hygiene products application, superabsorbent materials with antimicrobial activities are needed to prevent skin irritation. This research was developed to study the effects of chitosan’s weight in the superabsorbent polymers on the water absorbency, gel content, and Equilibrium Degree of Swelling (EDS). The polymer products were also characterized by FT-IR and SEM. Antimicrobial activity of the hydrogel against Escherichia coli was further investigated. An amount of 0,75 g of chitosan in the reaction mixture resulted in a grafted polymer after Υ-Rays irradiation with the best absorption (420 g g-1 in distilled water, 403,33 g g-1 in 0,009% NaCl solution, and 640 g g-1 in 0,9% urea solution). The gel content as high as 96,85% and EDS as high as 666,67 g g-1 of its dried weight were also obtained by using of 0,75 g of chitosan. The hydrogel was found to be effective against Escherichia coli.
