Abstract

An anion-exchange resin was modified with metal-tetrakis(4-sulfophenyl)porphine (M-TSPP) by ion-exchange reaction and physical adsorption, and silica gels and glass beads were modified by using the acid chloride of metal-tetrakis(4-carboxyphenyl)porphine (M-TCPP) through the peptide bond. The supports modified with Co³⁺-porphine were proved to accelerate the following redox reaction(s), of which the former is also catalyzed by ascorbate-oxidase (AsA): ASO_x or supports modified with M-porphine 2 Ascorbate (AsA) +O² → 2 Dehydroascorbate (DhAsA) +2H₂O supports modified with M-porphine Ascorbate (AsA) +O₂ → Dehydroascorbate (DhAsA) +H₂O₂ Formation of DhAsA and hydrogen peroxide was confirmed by means of mass spectroscopy and colored reaction, respectively. The supports modified with Co³⁺-porphine would be useful in practice as solid catalysts for the determination of AsA and for the removal of AsA which interferes with the determination of vital materials in clinical assays.
