発明の名称 (英語) ELECTROCHEMICAL QUANTIFICATION METHOD FOR HYDROGEN PEROXIDE
発明の概要(英語) Disclosed is an electrochemical quantification method for hydrogen peroxide, which does not generate oxygen in an electrochemical reaction of hydrogen peroxide on a sensing electrode, and does not induce any reaction by dissolved oxygen contained in a test sample solution, and in which the sensing electrode is chemically stable against the reaction of hydrogen peroxide and the material of the electrode itself does not undergo oxidation, the influence by an interfering component that is contained in the test sample solution and interferes with the electrochemical reaction of hydrogen peroxide directly or interferes with the current measurement that relies only on the electrochemical reaction of hydrogen peroxide is suppressed, the sensitivity can be maintained at a high level steadily for a long period, and any complicated calibration procedure for a sensor is not required. Specifically disclosed is an electrochemical quantification method for hydrogen peroxide, which is characterized by comprising the steps of: oxidizing a target substance (which has been delivered to a sensor) through an enzymatic reaction to generate hydrogen peroxide; and measuring a current generated in an electrochemical reaction of hydrogen peroxide, wherein the current to be measured is a current generated upon the reduction of hydrogen peroxide on a sensing electrode having, formed therein, a catalyst layer comprising amorphous iridium oxide.
