Study on the liquid-liquid equilibria and the mass transfer of emulsion liquid membrane during extraction

摘要：

This paper concerns with the liquid-liquid mass transfer and the liquid-liquid equilibria of butanone and dichloromethane in emulsion liquid membrane(ELM). The results show that there is about 88% of total mass transfer resistance concentrated on the interface due to surfactant monomolecular layer. The diffusion coefficient of dichloromethane in surfactant layer is 1.49 × 10 -14 m 2 / s. The liquid-liquid mass transfer cofficient increase with temperature and stirring speed. The liquid-liquid distribution coefficient decrease with temperature and the concentration of surfactant. It was shown that water solubility enhancements of butanone and dichloromethane was observed. The values of the chemical potential of butanone and dichloromethane in emulsion
