摘要
本文用国内的膜材料设计了以2-乙基已基膦酸单(2-乙基已基)酯(HEH(EHF),P_(507))为载体的支撑液膜迁移钴的实验,获得的数据为深入实验提供了依据.基本原理支撑液膜(SLM)是依靠微孔塑料薄膜(支撑体)微孔的毛细管作用将含萃取剂(载体)的有机溶液吸附在支撑体上.P_(507)萃取钴表示为:
The rate of cobalt transport through a supported liquid membrane containing (HEH(EHP),P507) as a mobile carrier has been studied. The influence of the stirring rate, pH, acetate concentration, carrier concentration, surfactant was investigated. In our experiment conditions the limiting thickness of the aqueous diffusion film is the same order of magnitude as the membrane thickness (2×10-3cm), the order of magnitude of the diffusion coefficient of the cobalt-HEH(EHP) complex in the SLM is l0-7cm2 / sec.
