Abstract
A method of preparing a trihalide resin, where a trihalide ion solution is contacted with a styrene divinylbenzene polymer resin having polymer bonded -ERXgroups where E is N, P, or As, R is a hydrocarbon group and X is Cl, Br, or I. The trihalide ion can be Cl, Bror I. A trichloride resin and a method of preparing the trichloride resin, where a styrene divinylbenzene polymer resin having polymer bonded -ERClgroups is contacted with chlorine. The trichloride resin can be used as a solid equivalent of chlorine gas. Formation of the styrene divinylbenzene resin comprising -ERClunits can be used to scavenge chlorine from a gas or liquid to form the styrene divinylbenzene resin comprising -ERClunits.
