中文摘要：

为商业地可得到的芳香的聚酰胺颠倒渗透膜的 Crosslinking 处理被执行改进它的氯抵抗。包括有与 NH 组一起的长灵活的脂肪族的链和高反应的 1,6-hexanediol diglycidyl 醚， adipoyl 二氯化物和 hexamethylene diisocyanate 酉旨的 crosslinking 代理人在实验被使用。稀释全部的反射 Fourier 变换红外线的系列验证了成功的准备高度由 crosslinking 处理的 crosslinked 膜。crosslinking 代理人与胺和酰胺 II 组通过反应被连接到膜表面，这被建议，它被表面费用大小证实。基于接触角度大小， crosslinking 处理减少了由把甲又组介绍给膜表面的膜 hydrophilicity。与增加代理人分子连接了到膜表面的 crosslinking 的数量， crosslinking 代理人的不连接的功能的组的水解作用生产了极的组并且增加了膜 hydrophilicity。高度，显示出的 crosslinked 膜更高作为与未加工的膜相比腌拒绝和更低的水流动。自从活跃地点(NH 组) 对膜表面上的免费的氯脆弱被 crosslinking 处理消除，氯电阻高度， crosslinked 膜被更细微的变化显著地在氯化以后在水流动和盐拒绝改进。

英文摘要：

Crosslinking treatments for a commercially available aromatic polyamide reverse osmosis membrane were carried out to improve its chlorine resistance.The crosslinking agents including 1,6-hexanediol diglycidyl ether,adipoyl dichloride and hexamethylene diisocyanate ester with long flexible aliphatic chains and high reactivity with N-H groups were used in the experiments.Attenuated total reflective Fourier transform infrared spectra verified the successful preparation of highly crosslinked membranes by crosslinking treatments.It was suggested that the crosslinking agents were connected to membrane surface through the reactions with amine and amide Ⅱ groups,which is confirmed by surface charge measurements.Based on contact angle measurements,crosslinking treatments decreased membrane hydrophilicity by introducing methylene groups to membrane surface.With increasing amount of crosslinking agent molecules connected to membrane surface,the hydrolysis of unconnected functional groups of crosslinking agent produced polar groups and increased membrane hydrophilicity.The highly crosslinked membranes showed higher salt rejections and lower water fluxes as compared with the raw membrane.Since the active sites（N-H groups） vulnerable to free chlorine on membrane surface were eliminated by crosslinking treatments,the chlorine resistances of the highly crosslinked membranes were significantly improved by slighter changes in both water fluxes and salt rejections after chlorination.
