摘要
提出了改进的Ⅱ型促进迁移液膜传质渐进前沿模型,该模型不仅考虑了滴内外扩散阻力、外界面反应,还同时引进了乳液渗透溶胀和液膜破损效应。用间歇式液膜提取苯丙氨酸进行了定量验证。模型计算值和实验值吻合良好。
An improved advancing front model for type II facilitated transport has been developed. The proposed model not only takes into account the mass transfer both inside and outside the emulsion globules , the interfacial chemical reaction, but also the influence of the permeation swelling and the breakage. Computer simulation was performed by the Crank - Nicolson implicit method. The results indicate that the process of computation is converged steadily and the model prediction agrees well with the experimental data.
