Abstract

A systematic study is presented on the extraction of Zr(IV) by tri-n-butylphosphate from H2SO4, HNO3, HCl and HBr solutions as well from binary mixtures of H2SO4 and halogen acids. It has been found that Zr(IV) extraction is appreciably increased by addition of halogen acid to sulphuric acid solutions. On the other hand, the presence of water-miscible alcohols and acetone was found to enhance Zr(IV) extraction from HCl and HNO3 solutions. An investigation of extracted Zr complexes from pure acids and mixed aqueous media enabled an explanation of the observed enhancements. In the light of the obtained results, an extraction mechanism is suggested.
