The adsorption of uranium form UO/sub 2/Cl/sub 2/ solutions containing HCl, NH/sub 4/Cl, and HF has been studied using polyampholyte resins ANKF-1, ANKF-2, and ANKF-3D. The effects of HCl, NH/sub 4/Cl, and HF over broad concentration ranges on uranium adsorption have also been investigated. Based on adsorption data and the results of elemental analysis and IR spectroscopy conclusions have been drawn concerning the composition of adsorbed ions and their binding forms with functional groups. A mathematical model to describe the adsorption process has been proposed.
