摘要: 交联型含磺化呋喃环聚醚复合膜对无机水溶液和有机水溶液具有很好的分离功能[1],其中日本东丽的PEC-1000反渗透复合膜对碱金属和碱土金属离子表现出特别高的截留率,巳用于工业规模的一级海水淡化[2]。但这类膜材料的耐氧化氯解性尚不够理想,分离海水时,体系中需加入微量NaHSO3之类还原剂。

Abstract: The stability toward oxidation and chlorine attack for membranes based on the sulfonated crosslinked polyether condensates or co-condensates from furfuryl alcohol and tris(2-hydroxy-ethyl)isocyanurate was studied by means of internal reflection IR spectroscopy. The mechanisms of their oxidation and chlorinolysis have beon discussed.

Key words: furfuryl alcohol resin, reverse osmosis membrane, ATR spectra
