Abstract

The effect of gel composition, absorbed dose and pH of the solution on the uranyl ion uptake capacity of N-isopropylacrylamide/maleic acid copolymeric hydrogels containing 0-3mol% of maleic acid at 48kGy have been investigated. Uranyl uptake capacity of hydrogels are found to increase from 18.5 to 94.8mg [UO 2 2+]/g dry gel as the mole % of maleic acid content in the gel structure increased from 0 to 3. The percent swelling, equilibrium swelling and diffusion coefficient values have been evaluated for poly(N-isopropylacrylamide/maleic acid) hydrogels at 500ppm of uranyl nitrate solution.
