摘    要: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。分析了萃取效率同震荡时间、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。

关 键 词:关键词:溶剂萃取  233Pa  二异丙酮  萃取效率

Abstract:Solvent extraction behavior of Pa with Di-iso-propyl-ketone(DIPK) in benzene is studied using ~(233)Pa 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.
Keywords:solvent extraction  ~(233)Pa  DIPK  extraction efficiency
