中文摘要 |
討論聚乙烯醇縮甲醛膜(PVF)在水-氯化鈉系中之透過性,進而由Fick第二定律求出溶質在膜中之擴散係數。實驗結果得知:由雙面脫着,單面脫着及時間遲延(time lag)等三種方法所求得之擴散係數相當接近。溶質之擴散係數及透過係數不隨濃度而改變。由三種方法所求出之溶質擴散係數平均值,可求出溶質在膜中之分配係數。 |
英文摘要 |
The transport properties of polyvinyl formal membranes to aqueous solution of NaCl were studied. The distribution coefficients of solute were independently determined from time-lag measurement and desorption rate experiment. The agreement in the results was quite good. |
