摘要：
The interfacial reactions and thermodynamic properties of the emulsion liquid membrane on separation and concentration of chromium(III) were discussed. Interfacial chemical reaction equations of membrane phase with P204 and mass transfer mechanism of ELM system were determined. The extraction reaction enthalpy is 11.41 kJ.mol(-1), while stripping reaction enthalpy is -143.65 kJ.mol(-1), were obtained by investigating reaction temperature on the distribution ratio under two different conditions. So extraction is an endothermic process and stripping is an exothermic process. And the main driving force of the separation system is the concentration gradient of hydrogen ion between external and internal phase interface.
