（Department of Chemical Engineering; Qinghua University; Beijing 100084; China）
Abstract:The equilibria and kinetic characteristics of a micelle mixed extractant system-D2 EHPA- MPA(MPA-monoalkyl phosphoric acid with long carbon chain and micellization)in extraction of the Al3+ ions were studied.It was found that the system has double synergistic effects on the extraction of the Al3+ ions.The compositions of the synergistic complexes were determined and the synergistic reaction equations were obtained.
Key words: D2EHPT-MPA mixed system; double synergistic effects; extraction kinetics extraction mechanism; micelle; mixed extractant system
