  surfactant
The optimal constituents of microemulsion were found from pseudoternary phase diagrams: the mass ratio of Span80 to PS was 4:1 and complex surfactant to cosurfactant was 1:1.
      
Synthesis and surface-active property of bis-quaternary ammonium-sodium sulfate Gemini surfactant
      
N,N-dimethyldodecylamine, hydrochloride and epichlorohydrin (molar ration is 2:1:1) were used to synthesize bis-quaternary ammonium Gemini surfactant with a hydroxyl in its spacer group by the one-pot method.
      
This hydroxyl was sulfonated by chlorosulfonic acid and then neutralized to bis-quaternary ammonium-sodium sulfate zwitterionic Gemini surfactant.
      
The critical micelle concentration (cmc) and surface tension of the novel zwitterionic Gemini surfactant in aqueous solution at 15°C are 7.2×10-5 mol/L and 34.5 mN/m, respectively.

This paper deals with the first part of the article. By studying the facilitated and the actiye transports of K~+ ion, a design of the liquid membrane system for the liquid surfactant membrane seperation and concentration of K~+ in practice is suggested. First, a suitable method of design is selected by determining the facilitated transport of K~+ ion in pure KCl, the form of- the apparatus used in this method being also changed in a proper way. Then, the facilitatid and the active transports of K~+ ion are investigated by means of this method. We predict that the presence of NaCl in KCl will cause an increase in the transport ratio of K~+, in the mean time, the Cl~- present is one source of energy necessary for the active transport of K. Furthermore, we also predict that the transport ratios of K~+ in both facilitated and active transports. will be further increased if the Cl~- present is replaced by Br~- or I~-. The experimental results are consistent with the predictions. Finally, a concret design is suggested.

本文是本题的第一部分,目的是通过对钾离子的促进迁移和活性迁移的研究,为实用性的K~+离子表面活性剂液膜分离与浓缩提供关于液膜体系的设计方案。首先,通过纯KCl中K~+离子的促进迁移的测定选择了设计方法,并适当地变换了所用装置的形式。用此方法进行了K~+离子的促进迁移和活性迁移的研究。预计当有NaCl存在时将提高KCl中K~+离子的促进迁移率。同时,此Cl~-离子的存在也可提供K~+离子的活性迁移所需要的能源。再者,预计用I~-离子或Br~-代替Cl~-离子将更进一步提高K~+离子的促进迁移率和潘性迁移率。实验结果与预计完全相符。最后提出了设计方案。

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.

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.
