摘　　要：通过制备油包水(W/O)乳状液并利用加电三维螺旋状微通道对W/O乳状液的快速高效破乳作用,探究了乳状液膜萃取柠檬黄及其油相回收的优化工艺.主要考察了乳水比和外水相pH值对乳状液膜分离效率的影响.实验结果表明:在搅拌转速为400 rpm、搅拌时间为5 min条件下,当乳水比为1:2、外水相pH=2、柠檬黄的初始浓度为100 mg·L^(-1)时,乳状液膜对于水溶液中的柠檬黄去除率最高可达77%.利用加电三维螺旋板式微通道对萃取后的乳状液进行破乳,其油相回收率可达82%.Emulsion membrane extraction of tartrazine was studied with water in oil（ W/O） emulsion,and three-dimension electric spiral plate-type microchannel（ 3D-ESPM） was used to recover the oil phase of emulsion. The effect of the ratio of emulsion to water（ Rew） and pH of tartrazine water solution on the tartrazine removal rate was experimented. Under the optimal condition of 400 rpm stirring for 5 min,Rew= 1： 2,pH = 2,the initial tartrazine concentration = 100 mg·L^（-1）,the tartrazine removal rate reached 77%. The recovery ratio of the oil phase was 82% with 3D-ESPM.
