Abstract

Peroxidase-like activity of anion-exchange resins modified With rnetal- tetrakis(sulfophenyl)porphine (M-TSPP(r), M=Fe 3+ , Co 3+ and Mn 3+ ) were evaluated in the flow injection analysis of hydrogen peroxide using a fluorescent dimmer-formation reaction from chromogens, such as tyramine. A column (2.1 mmx50 mm) packed with Fe 3+ -TSPP(r) and a tube (0.8 mmx50 mm) packed with Mn 3+ -TSPP(r) accelerated the dimmer-formation reaction, indicating that they exhibit peroxidase-like activity just like the peroxidase-immobilized-column in the flow injection system.
