Abstract

The distribution ratios of Zr(Ⅳ) and TcO-4 between 30%TBP/OK and aqueous solution of various concentrations Zr(Ⅳ), TcO-4 and HNO3 have been investigated. The results show that coextraction of Zr(Ⅳ) and TcO-4 has obvious mutual promotion effect--technetium in the form of anion TcO-4 can coordinate with Zr(Ⅳ) to form coextraction and promote extraction of Zr(Ⅳ).
