Abstract: The controlling reaction for the micelle mixed extractant system D2EHPA-MPA-Al3+ was proved to occur inside the micelle phase by the studies of extraction kinetics，extraction equilibria and interfacial chemistry. The extraction reaction mechanisms of the two components, i. e. the micelle mixed extractant system D2EHPA- MPA- A13+ and the single micelle extraction system MPA-Al3+，in the micelle phase and liquid-liquid interfacial reaction regions, were suggested. The extraction reaction rate equations were obtained and the acceleration mechanism and characteristics for the micelle mixed extractant system were discussed.
