The method is based on the nitrite catalysed discoloring re action of metanil yellow by potassium bromate, and the reduction of nitrate to nitrite by zinc powder.
本文基于NO2-对KBrO3氧化酸性间胺黄而使其褪色的催化作用，以及NO3-经锌粉还原为NO2-，建立了灵敏的催化光度测定痕量NO2-、NO3-的新方法，并讨论了其动力学条件。
A new kinetic spectrophotometric method for determination of micro amounts of iodide has been proposed, based on the principle that I- inhibits the discoloration of metanil yellow oxidized by potassium bromate in sulfuric acid medium and in the presence of sodium thiosulfate.
