Radiochemistry Aims and scope

Abstract

Extraction of HNO3, HCl, H2SO4, H3PO4, H3AsO4, HF, and H2C2O4 with triisoamyl phosphate (TiAP), diisooctyl methylphosphonate (DiOMP), isoamyldialkyl(C7-C9)phosphine oxide (DRPO), and cyclohexyldialkyl(C7-C9)phosphine oxide (DRPO-1Ts) was studied, and the extraction isotherms were obtained. The solvation numbers of certain acids and extractants were determined by dilution and saturation methods. Purification of wet-process phosphoric acid to remove arsenic was studied. Distribution of Cu, Zn, Ni, Co, Fe, and Mn microamounts in the oxalic acid-neutral organophosphorus compound (NOPC) extraction systems was measured, and the feasibility of purification of oxalic acid to remove these metals to a 10-7% content was demonstrated.
