稀硫酸介质中，痕量甲醛的存在对溴酸钾氧化甲基橙的反应有很强的催化作用。而甲基橙及其氧化产物均能在滴汞电极上产生灵敏的极谱吸附波。本文以极谱法测定催化反应过程中甲基橙浓度的变化，建立了催化动力学极谱法测定痕量甲醛的方法。

The existence of trace formaldehyde had a strong catalytic effect on the reaction of potassium bromate oxidation of methyl orange in the dilute sulphuric acid medium.Methyl orange and their oxidation products could produce sensitive polarographic adsorptive wave in the dropping mercury electrode. In this article the change of the concentration of methyl orange in the process of catalytic reaction was determined by the polarography. And the determination of trace formaldehyde was established by the kinetics of catalytic polarography method.
