高碘酸钾与甲基红的反应可为亚硝酸根所催化。本文报导了应用高氯酸根选择电极监测高碘酸根浓度改变,从而进行亚硝酸根测量的催化动力学电位分析法。对测试条件进行了试验。回收率试验及实际试样分析的结果均与传统的分光光度法相仿。
The reaction of potassium periodate with methyl red may be catalyzed by nitrite. In this paper, a catalytic kinetic potential analysis method for the measurement of nitrite with perchlorate selective electrode monitoring the change of periodate concentration is reported. The test conditions were tested. The results of the recovery test and the actual sample analysis are similar to the conventional spectrophotometry.
