【摘要】 本文用液相色谱的方法,测定了一些有机溶质在聚苯并咪唑酮(PBIL)膜与水之间的平衡分配系数K,并以此为基础,着重阐述了不同类型的有机溶质与PBIL膜之间相互作用的特点和反渗透分离过程中平衡效应与动态效应对分离性能的影响。从分子间的相互作用出发,探讨了反渗透分离机理,得出了较为令人满意的结果。更多还原

【Abstract】 In the paper,the method of liguid chromatography was used for mea-suring the partition coefficient K of some organic solutes (alchol,aldehydesand acids etc.)between PBIL membrane and water phases.It has beenfound that the solute—membrane interactions can be characterized byK.According to the data (K) that has been determined,it was discussedthat the mechanism of the RO separation.It has been shown that theequipment character and the dynamic property have a great influence uponthe separation function in reverse osmosis.更多还原
