Abstract

In this research, the absorption of uranium from sulfate solution containing uranium by strong basic anionic resin Amberlite IRA-402 has been investigated. the purpose of this study is to investigate the effect of pH parameters, the amount of adsorbent used, the initial concentration of uranium metal ions and contact time on the amount of uranium absorption from the solution obtained from the leaching of the ore in the batch system. The results obtained for uranium absorption showed that at pH 3, the amount of adsorbent used is 2g/l and the equilibrium time is 100 minutes, the maximum amount of absorption occurs. In the study of the effect of concentration on uranium absorption, it was observed that with the increase of the initial concentration of metal ions, the absorption percentage decreases, but the absorption rate per gram unit of the adsorbent increases. The results of kinetic experiments in optimal conditions for uranium absorption and matching the experimental data with the first-order and second-order kinetic models showed that the process of uranium absorption by Amberlite IRA-402 resin follows the pseudo-second-order kinetic model.
