| Abstract: | ![]()
The hydrolysis rate of reverse osmosis membrane of cyanoethyl cellu-lose acetate (CECA) was studied in acid medium.The reason for the goodacid resistance of CECA was discussed.It was found that the hydrolysisrate of acetyl group was not affected by the existence of cyanoethylgroup,but the weight loss caused by the hydrolysis of acetyl group waspartly compensated because cyanoethyl group hydrolyzed to carboxethylgroup.Therefore,the acid resistance of CECA reverse osmosis membranewas better than that of cellulose acetate. |
