N2 - the ion-exchange resins modified with metal-porphyrins and -phthalocyanines (M-Pr) have been found to exhibit a peroxidase (POD)-like activity on organic peroxides in a reaction wherein a quinoid dye is formed from phenol and 4-aminoantipyrine. Among them, Mn- and Co-Pr exhibited stronger activity than hemoglobin and Fe-Pr, and hence were expected to be practically useful as a solid catalyst for the determination of linoleate hydroperoxide (LOOH). In addition, a resin modified with Co3+ -phthalocyanine tetrasulfonate (Co-PCSr) lacks POD-like activity on hydrogen peroxide in contrast with Mn-Pr. We, therefore, concluded that Co-PCSr is superior to both Mn-Pr and hemoglobin as a solid catalyst on organic hydroperoxides, and developed a new method for the determination of LOOH.
