镧离子(Ⅲ)在HPMBP为载体的大块液膜中的传输

Transport of La(Ⅲ) Through Bulk Liquid Membrane Using 1 Phenyl 3 Methyl 4 Benzoly 5 Pyrozolone (HPMBP) as Carrier

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、料液浓度及温度对Ｌａ（Ⅲ）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浓度增加，反萃液盐酸浓度增加，料液ｐＨ值增大，料液浓度减小，温度升高均有利于Ｌａ（Ⅲ）的迁移．实验中发现Ｌａ（Ⅲ）在膜迁移中有滞留现象。

The coupled transport of La(Ⅲ) 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 and concentration of La(Ⅲ) in feed solution and temperature.When La(Ⅲ) is transferred by the bulk liquid membrane there is a measurable accumulation of La(Ⅲ) in the membrane.The good explanation of the phenomenon is given with membrane potential.
