Role of electron beam irradiation on superabsorbent behaviors of carboxymethyl cellulose

Role of electron beam irradiation on superabsorbent behaviors of carboxymethyl cellulose Superabsorbent materials derived from synthetic polymers can cause various environmental problems. In this study, eco-friendly superabsorbent materials were prepared from a mixture of carboxymethyl cellulose (CMC) as a raw material and different concentrations of citric acid (CA) as a crosslinking agent through electron beam irradiation (EBI). The results showed that the CMC/2 wt% CA and CMC/4 wt% CA samples obtained using 20-kGy EBI showed the highest gel fraction value of over 95 % and the highest swelling degree of around 7,000 %. In addition, the water retention of the swollen CMC/2 wt% CA gel decreased steadily to around 63 % of the initial absorbed water during a period of 7 h, and then remained at around 60 %.
