摘要
建立的乳状液膜体系中，稀土离子由内水相向外水相迁移的传质模型，探讨了该液膜体系的传质机理．实验结果表明，本文模型准确地描述了液膜体系的传质行为。
A mass transfer model is developed to describe mass transfer behavior of rare earth which diffuses from the internal aqueous phase to the external aqueous phase in emulsion liquid membrane system. The mass transfer mechanism is investigated. The experimental results show that the proposed model accurately describes mass transfer process of emulsion liquid membrane system. The diffusional resistances of the species in the internal boundary layer and membrane phase are main mass transfer resistance.
