Abstract

Some of the ion-exchange resins modified with metalloporphyrins have been found to exhibit glutathione-peroxidase (GSHPx)-like catalytic activities for hydrogen peroxide and cumene hydroperoxide in the oxidative reaction of glutathione to disulfide. In particular, the anion-exchange resin modified with Mn(III)-tetrakis(sulfophenyl)porphine (Mn-TSPP r ) exhibited stronger activity than GSHP x , and hence Mn-TSPP r was expected to be a good mimesis in place of GSHP x or immobilized GSHP x for the determination of peroxide.
