This paper is a succeeding work of “An Investigation of Liquid Membrane Seperation of K~+ Ion-Facilitated and Active Transports of K+” in which a preliminary design of a liquid membrane system was presented. In order to make this design for use in practice, the system must be further designed in an emulsion form. Thus, the type of surfactant to use, the techniques of emulsification and demulsification, the further selection of organic solvent and the efficiency of seperating K~+ etc. are investigated in this...

This paper is a succeeding work of “An Investigation of Liquid Membrane Seperation of K~+ Ion-Facilitated and Active Transports of K+” in which a preliminary design of a liquid membrane system was presented. In order to make this design for use in practice, the system must be further designed in an emulsion form. Thus, the type of surfactant to use, the techniques of emulsification and demulsification, the further selection of organic solvent and the efficiency of seperating K~+ etc. are investigated in this paper. No commercial surfactant can be used successfully, the surfactant used is prepared by the authors themselves (named LMS-1). The new method of demulsificatisn used in this design is developed by the authors themselves too.
