摘　　要：采用恒界面池法 ,对我们所建立的乳状液膜提取铂的体系进行了表观动力学研究 ,确定了其提取过程的速控类型 ,确立了其表观动力学方程 .The kinetics of extraction of Platinum (Ⅳ) from artificial Wastewater Solution with emulsion liquid membrane has been studied. We have used Lewis cell technique. The effect of temperature, stirring speed and the component of outer aqueous phase and emulsion liquid membrane on the platinum (Ⅳ) extraction rate were examined. The regularity of extraction of the platinum extraction rate has been obtained. The rate control type of extraction process and the matter transfer mechanism have been given.
