Abstract

Extraction of lanthanide(Ⅲ) was studied using heptane containing bis(2-ethylhexyl)phosphinic acid in perchlorate medium.Also,this paper discusses the effect of extraction equilibrium time,different medium,PIA-8 concentration upon extraction of lanthanide(Ⅲ) and extracting agent concentration upon counterextraction efficiency;The composition of the extracted compound was shown to be La(HA_(2))_(3).The pH_(1/2)values of La~(3+),Ce~(3+),Pr~(3+),Nd~(3+),Sm~(3+),Eu~(3+)are 3.69,3.30,3.16,3.10,2.68 and 2.54 respectively.
