以人红细胞作为过氧化氢酶的来源，用尼龙网共价键合，并与氧电极偶合制得过氧化氢传感器，研究了尼龙网上活化酶的固定化，测试介质等有关实验条件和参数。测得在ｐＨ８的磷酸盐缓冲溶液中，电极响应的线性范围为３×１０－５～３×１０－３ｍｏｌ／Ｌ，测定了传感器在果珍，鱼浆和磷酸盐缓冲溶液中对过氧化氢的回收率，获得满意结果。 Using human erythrocytes as catalase source, covalently bonded with nylon mesh and hydrogen peroxide sensor coupled with oxygen electrode, the experimental conditions and parameters of immobilization and test medium of nylon net activator were studied. The pH value of the phosphate buffer solution was measured in the linear response of the electrode in the range of 3 × 10-5 ~ 3 × 10-3mol / L, measured the sensor in the fruit Jane, fish slurry and phosphate buffer solution of hydrogen peroxide The recovery rate, to obtain satisfactory results.
