Abstract
The effect of external stimuli such as pH of the solution, ionic strength a nd temperature on the uranyl ions uptake capacity of poly(N-vinyl 2-pyrroli done/itaconic acid) (P(VP/IA)) hydrogels was investigated. Polyelectrolyte P(VP/IA) hydrogels with varying compositions were prepared in the form of r ods from ternary mixtures of N-vinyl 2-pyrrolidone/itaconic acid/water. Ura nyl adsorption capacity of hydrogels were found to increase from 26.7 to 70 (mg UO22+/g dry gel) with decreasing pH of the swelling solution. Adsorpti on studies have shown that other stimuli, such as temperature and ionic str ength of the swelling solution have also influence on the uranyl ions uptak e capacity of P(VP/IA) hydrogels.
