| Abstract: | The transfer behavior of Y() through the emulsion liquid membrane system of TBPLMS2sulfonated kerosene was studied. The efficiency and speed of transfer of Y() are very high under the followingconditions: membrane phase:5.0%(V/V)TBP 2.0%(V/V)KMS2 93%(V/V); internal phase: 0.10mol/dm3NaHCO3, external phase: pH=3,6mol/dm3NH4NO3 as medium. In this case, some coexisting ions such as Fe2 , Co2 , Ni2 and Zn2 cannot transfer through this emulsion liquid membrane. So Y() can be separated from these ions and has a recovrey rate of more than 98%. |
