| Abstract: | In this paper,removing and recovery of Cr (Ⅵ)with emulsion liquid membrane is described. Components of liquid membrane,including memdrane solvent,carrier and surfactant,are optimized. The effects of some factors such as PH of internal and extranous phase,dose of carrier,the time and stirring viloc.ity of emulsion-causing and of mixing emulsion and extranous phase,the rate of membrane phase and internal phase,the rate of emulsion and extranous phase,on the results of removing Cr(VI)are tested. The study indicate:the removing rate of Cr(Ⅵ)is over 95%. |
