Synthesis of Anionic Hydrogels for Uranyl Ion Adsorption

Abstract

In this study, the anionic hydrogels were prepared in existence of crosslinker (N, N’-methylenebisacrylamide) by free radical addition reaction in aqueous solutions of neutral acrylamide and 2-hydoxyethyl methacrylate monomers and anionic comonomers such as mesaconic acid with 2 carboxyl groups or aconitic acid with 3 carboxyl groups.

Hydrogels were characterized by FT-IR and DSC analysis. The effects of temperature, pH, adsorbent mass and concentration on uranyl ion adsorption onto the anionic hydrogels were investigated.

It was determined that adsorption of UO₂²⁺ ions to prepared hydrogels did not change with temperature and increased with increasing pH.

The adsorption of uranyl ion from aqueous solutions onto the anionic hydrogels was evaluated by applying Giles, Langmuir and Temkin isotherms to experimental results.

According to the Giles adsorption isotherms classification of hydrogels UO₂²⁺ ions adsorption prepared from adsorption isotherms formed, L type was determined and Langmuir parameters were calculated.

It was determined that adsorption of UO₂²⁺ions to hydrogels prepared from R_L values calculated for 1000 mg L^-1UO₂²⁺ ion concentration is favorable.
