Construction of a New Emulsion Film for the Extraction and Separation of Re(Ⅲ)
Aiming at the difficulty of extracting and separating of high purity single rare earth elements or compounds,a new emulsion liquid film was constructed and used for the extraction and separation of Re(Ⅲ)(La3+,Ce3+,Pr3+,Nd3+).The types and concentrations of mobile carriers and surfactants,and the internal water phase in liquid film system were determined by single factor experiment.The results show that the optimal composition of the emulsion liquid membrane system is 6％D2EHPA,5％T154,3 mol/L HCl solution,phase ratio Roi=1.5.The emulsion film constructed in this system has stable phase and excellent extraction effect,and can realize efficient separation of Re(Ⅲ).
