- Abstract
- In this study, adsorptions of uranyl ions from two different aqueous
uranyl solutions by acrylamide-itaconic acid hydrogels were investigated by
a spectroscopic method. The hydrogels were prepared by irradiating with
gamma-radiation. In the experiment of uranyl ions adsorption, Type II
adsorption was found. One gram of acrylamide-itaconic acid hydrogels sorbed
178-219 mg uranyl ions from the solutions of uranyl acetate, 42-76 mg uranyl
ions from the aqueous solutions of uranyl nitrate, while acrylamide hydrogel
did not sorb any uranyl ion. For the hydrogel containing 40 mg of itaconic
acid and irradiated to 3.73 kGy, swelling of the hydrogels was observed in
water (1660%), in the aqueous solution of uranyl acetate (730%), and in the
aqueous solution of uranyl nitrate (580%). Diffusions of water onto
hydrogels were a non-Fickian type of diffusion, whereas diffusions of uranyl
ions were a Fickian type of diffusion. [References: 25]
