摘要：

In this paper, removal and recovery of Cr(Ⅵ) with emulsion liquid membrane are described. Components of liquid membrane, including membrane solvent, carrier and surfactant, are optimized. The effects of some factors such as pH of internal and extraneous phase, dose of carrier, the time and stirring vilocity of emulsion-causing and of mixing emulsion and extranous phase, the ratio of membrane phase to internal phase, the ratio of emulsion to extranous phase, on the results of removing Cr(Ⅵ) are tested. The results indicate that the removal rate of Cr(Ⅵ) is over 95%.
