The interfacial chemistry, synergistic effects and interfacial kinetics of thesynergistic extraction system D_2EHPA-MPA-Fe~(3+) have been studied, where MPA is amono-alkyl phosphate extraction with long carbon chain. D_2EHPA in the mixed extractionsystem strongly exhibits the effect on the thermodynamics of micella formation and interfaceproperties of MPA. Some thermodynamic parameters of micella formation were obtained.The interfacial adsorption behaviour of D_2EHPA is opposite to that of MPA. Theemulsification for single MPA and the mixed system was discussed. The synergistic effectswere found in this mixed extraction system. It is proved that the process of Fe~(3+) extractionfor non-mixed extraction system is controlled by chemical reaction, the controlling reactionoccurs at the interface, and the reaction rate equation is obtained.
