摘要

AbstractThe applicability of membrane‐reservoir devices based on cold water insoluble, fully hydrolyzed poly(vinyl alcohol) (PVA) membranes for the controlled release of chlorinated isocyanurates into aqueous media has been demonstrated. In addition to providing a prolonged constant rate of release, fully hydrolyzed PVA membranes also exhibit, good stability in the presence of saturated solutions of chlorinated isocyanurates. The apparent resistance to degradation by chlorine and the significant retention of wet mechanical strength of these membranes have been attributed to the semicrystalline nature of PVA. © 1993 John WileySons, I
