METHOD FOR REMOVING REDUCTION-TYPE ASCORBIC ACID, URIC ACID OR HYDROGEN PEROXIDE

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently removing reduction-type ascorbic acid, uric acid or hydrogen peroxide as error factor in measurement at the time of quantitatively and qualitatively analyzing a specified substance in soln. or a method for efficiently removing hydrogen peroxide used in sterilization. ;SOLUTION: Reduction-type ascorbic acid, uric acid or hydrogen peroxide is oxidized with a water-insoluble substance having a higher standard oxidation- reduction potential than the materials and removed. Polypyrrole, tetracyanoquinodimethane, titanium oxide, etc., for example, are used as the water-insoluble substance, and polypyrrole is preferably used among them.;COPYRIGHT: (C)1999,JPO
