摘要
用233Pa作示踪剂,苯作稀释剂,研究了二异丙酮(Di-iso-propyl-ketone)对Pa的溶剂萃取行为。分析了萃取效率与震荡时间、不同种类的无机酸浓度和萃取剂浓度的关系及F-对Pa溶剂萃取的影响。结果表明,二异丙酮是萃取Pa的一种优良的萃取剂;二异丙酮-盐酸体系适用于Pa的萃取研究。
Solvent extraction behavior of Pa with Di-iso-propyl-ketone （DIPK） in benzene is studied using ^233pa as a tracer. The extraction efficiency of protactinium is measured under the conditions of shaking time, concentrations of different acid and extractant concentrations. The effect of F^- is also investigated. The results show that DIPK is an excellent extractant for protactinium and DIPK-HCl system is suitable for the extraction of Pa.
