    • PROBLEM TO BE SOLVED: To solve the problems wherein, when measuring the concentration of hydrogen peroxide using an electrode sensor, accurate measurement of the concentration of hydrogen peroxide is possible if only reduction of hydrogen peroxide is generated on the electrode, while actually accurate measurement of the concentration is impossible because catalytic decomposition of hydrogen peroxide or generation of hydrogen peroxide by reduction of oxygen proceeds simultaneously. SOLUTION: This hydrogen peroxide reduction electrode 2 is formed by adsorbing at least one kind of adsorption species selected from halide ion, sulfur ion and thiol compounds onto a conductive substrate surface in the fixed state. The electrode surface is coated by the adsorption species, and thereby catalytic decomposition of hydrogen peroxide or generation of hydrogen peroxide by reduction of oxygen is prevented, and only reduction of hydrogen peroxide is generated on the electrode. Consequently, accurate concentration measurement becomes possible. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题为了解决当使用电极传感器测量过氧化氢浓度时,如果在电极上仅产生过氧化氢的还原,则可以准确测量过氧化氢的浓度,而实际上 精确测量浓度是不可能的,因为过氧化氢的催化分解或通过还原氧产生过氧化氢同时进行。 解决方案:该过氧化氢还原电极2通过在固定状态下吸附选自卤离子,硫离子和硫醇化合物的至少一种吸附物质形成在导电基材表面上。 电极表面被吸附物质包覆,从而防止过氧化氢的催化分解或通过还原氧而产生过氧化氢,并且在电极上仅产生过氧化氢的还原。 因此,精确的浓度测量成为可能。 版权所有(C)2007,JPO&INPIT
