Abstract

A systematic study is presented on the extraction of60Co and65Zn bromides and chlorides from H2SO4 with tri-n-butyl phosphate (TBP) and Amberlite LA-2. It has been found that the presence of a little HBr or HCl enhances the extraction of the two isotopes with both solvents. The extractions of60Co and65Zn have been studied as functions of the acidity (HBr, HCl or H2SO4) in the aqueous phase, and of the diluent and solvent concentrations in the organic phase. The presence of water-miscible alcohols or acetone enhances extraction. A suggested extraction mechanism is presented in the light of the obtained results.
