摘　　要：用Ｌｅｗｉｓ恒界面传质池对乳状液膜分离Ｚｎ２＋的传质阻力进行实验研究，结果表明由于表面活性剂单分子层的形成，使界面传质阻力占整个传质阻力的８５％。The mass transfer resistance research of zinc extraction by emulsion liquid membranes using Lewis constant interfacial area cell has been conducted.The results show that there is about 85% of total mass transfer resistance concentrated on interface due to surfactant monomolecular layer. So, a simplified mass transfer model of zinc extraction by emulsion liquid membrane which considers the factors of interfacial resistance and membrane breakage has been adopted in this investigation.The agreement between calculated and experimental results is satisfactory.
