| Abstract: | A toluene emulsion liquid membrane has been prepared. Transportation behaviors of metal lons in this kind of liquid membrane system have been studied, when inner phase reagents are EDTA ,Na4P2O7 ,Na2S2O3 ,HNO3 etc. respectively. Transportation mechanism of the emulsion liquid membrane was discussed. Optimum conditions were selected for separation of Lead (I),Zinc (I),Cadmium and Mercury. |
