Recovery of uranium from beryllium-containing solutions with organic sorbents

Radiochemistry Aims and scope

Abstract

Recovery of uranium with various sorbents from spent multicomponent solutions that are formed upon decontamination of beryllium items and contain uranium, beryllium, and aluminum complexes and sodium and fluoride ions was studied. Unsymmetrical phosphine oxide solid extractant (UPO-SE) showed better characteristics in the process than the ion exchangers studied (KU-2, SF-5, KB-4). Along with high performance, UPO-SE exhibits high selectivity in the presence of Be(II) ions. The main process parameters of uranium recovery, allowing calculation of the apparatus for the industrial sorption process with the possibility of multiple use of process solutions for decontamination, were determined.
