• 中文摘要： 液態薄膜系統是兩種完全互溶的液體經由和這兩種互不溶的液體分開而形成的,本文是用含有NaOH的水溶液擴散在油性溶劑的油滴中,而此油滴再經慢速攪拌而散佈在含有酚的水中(Water/Oil/Water System),酚由外相的水中經過油性溶劑質傳到內相和NaOH反應成為鹽類,而此鹽類則不溶於油性溶劑,因此能把外相的酚降到相當的低。本文提出批式操作中去除酚的質傳數學模式,利用一些可預測的參數,再加上本文的數學模式,即可預測在各種不同條件下酚的去除速率,本文所預測的值和文獻上的實驗值,相當的吻合。
• 英文摘要： A mathematical model with an analytical solution for the phenol removal from a dilute solution by dispersed liquid membranes is developed for a batch process to describe the phenomena of phenol diffusion from external bulk solution through liquid membrane into internal droplet. In the model Sauter mean diameter of globules is used. Chemical equilibrium is assumed and film resistances are considered at membrane external and internal interphases. All parameters of the model can be determined before a phenol removal experiment, and the phenol removal rate can be predicted theoretically. Model with or without the consideration of film resistances are compared with experimental data. Results indicate that the model considering the film resistances gives the best representation of the experimental data.
