Abstract:
In this study, irradiation technique was used to produce copolymer AAc-g-PVP with different ratios of acrylic acid (AAc) and polyvinyl pyrrolidone (PVP). The results showed that copolymer hydrogel with AAc/PVP ratio 3:1 (w/w) had the highest gel content (94.88%) and water swelling degree was found to be 4 g/g at an adsorbed dose of 20 kGy. The ability to adsorb Pb2+, Cu2+, Mn2+,and Cd2+ ions of copolymer have been carried out. Results on adsorption isotherm models show that the adsorption of ions of the copolymer is consistent with the Langmuir adsorption model with a high correlation coefficient (R2 〉 0.99). The maximum adsorption capacities are 244, 222, 167, and 170 mg/g for Pb2+, Cu2+, Mn2+, and Cd2+, respectively. The AAc-g-PVP copolymer hydrogel material has potential applications for adsorbing heavy metal ions in water.
