OXIDATIONSBESTAENDIGE IONENAUSTAUSCHERHARZE UND VERWENDUNG DERSELBEN BEI DER BESEITIGUNG VON KATIONEN AUS OXIDATIONSMITTELHALTIGEN LOESUNGEN

摘要

An oxidation resistant ion exchange resin, which is particularly useful for removing cations from an oxidative agent-containing solution such as chromium-plating solution, is produced by halogenation of an ion exchange resin. In Examples, sulphonated styrene/divinylbenzene copolymer resins are reacted with Cl2, Br2 or F2.
