| Abstract: | In this work emulsion liquid membrane which contained LYF（sulphonated polybutadiene） as surfactant,P204 as carrier,was applied to removal of lanthanides.Results show that the modified way is successful on the preparation of LYF and simpler.The degree of removal of lanthanides could be 86.67% with aqueous/organic phase ratio=2：1,P2O5%=15%,concentration of La3＋=300 mg/L. |
