Abstract

The present flow analysis of hydrogen peroxide is based on a measurement of the absorbance of quinoid-dye formed by a following reaction (1) using an anion-exchange resin modified with manganese(III)-tetrakis(sulfophenyl)porphine (Mn-TSPPr), which catalyzes the reaction (1), just like an immobilized peroxidase: 4-aminoantipyrine+4-chlorophenol+2H2O2Mn-TSPPr quinoid dye+4H2O [reaction (1)]. Mn-TSPPr is more advantageous than immobilized peroxidase in terms of storage and stability for both temperature and moisture. The present facilitated method is satisfactory in reproducibility and sensitivity.
