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。
With 233Pa as a tracer and benzene as a diluent, the solvent extraction behavior of Pa with Di-iso-propyl-ketone was studied. The relationship between extraction efficiency and shaking time, different kinds of inorganic acid concentration and extractant concentration and the effect of F- on Pa solvent extraction were analyzed. The results showed that diisopropyl ketone was an excellent extractant for extracting Pa. Diisopropanic acid-hydrochloric acid system was suitable for the extraction of Pa.
