正丙醇-水体系中SbI_4^-与U(Ⅶ)、Ce^(3+)、Co^(2+)和Ag^+的析相萃取分离

Extraction Separation of SbI_4^- from U(Ⅵ),Ce^(3+),Co^(2+) and Ag^+ in Water-n-Propyl Alcohol System by Phase Separation Extraction

研究了正丙醇-水体系析相萃取分离和富集SbI4-的行为及其与一些金属离子分离的条件。实验表明,控制pH为2,能使SbI4-与U()、Ce3+、Co2+和Ag+分离。

The behavior of extraction separation and concentration of SbI-4 in water-n-propyl alcohol system and conditions of separation of SbI-4 from other metal ions were investigated by phase separation extraction.SbI-4 can be separated completely from U（Ⅵ）,Ce3＋,Co2＋ and Ag＋ with controlling pH of 2.
