Abstract: The design of a liquid membrane system for the liquid surfactant membrane seperation and concentration of K+ for use in practice is presented. First, a suitable method of design is selected, the form of the apparatus used in this method being changed in a proper way. Then, the facilitated and the active transports of K+ are investigated. We predict:(1)the presence of NaCl in KCl will cause an increase in the flow of K+;(2) this Cl- present may be one source of energy necessary for the active transport of K+;(3)the flow of K+ will be further increased if the Cl- present is replaced by Br- or I-. The experimental results are consistent with the predictions. Finally, a concrete design is suggested.

摘要： 本文目的是设计一个实用性K~+表面活性剂液膜分离的液膜体系。作者选择了一个合适的设计方法并对此法中所用装置作了适当的改变后,研究了K~+的促进迁移与活性迁移。作者预计:（1）KCl中含有NaCl时将使K~+的迁移量增加。（2）此Cl~-可作为K~+活性迁移所必需的能源。（3）如果用Br~-或I~-代替Cl~-将进一步使K~+的迁移量增加。实验结果均与预计相符。最后,提出了具体的设计方案。
