摘要
研究了在ＨＰＭＢＰ－ＣＨＣｌ３大块液膜体系中，载体浓度、反萃液酸度、料液ｐＨ值及温度对Ｅｕ３＋迁移的影响，筛选出了能顺利测出膜电位的支持电解质．结果表明，ＨＰＭＢＰ浓度和反萃液盐酸浓度增加、料液ｐＨ值增大、温度升高均有利于Ｅｕ３＋的迁移．实验发现Ｅｕ３＋在膜迁移中有滞留现象，并首次用膜电位作了分析．
The coupled transport of Eu 3+ and H + through a bulk liquid membrane consisting of HPMBP and chloroform has been studied as a function of carrier concentration, hydrochloric acid concentration in strip solution,pH in feed solution and temperature.When Eu 3+ is transferred by the bulk liquid membrane there is a measurable accumulation of Eu 3+ in the membrane.The good explanation of the phenomenon is given with membrane potential.
