摘要
本文基于酸性介质中亚硝酸根对氯酸钾氧化亮甲酚兰使其褪色所起的催化作用，建立了高灵敏度催化光度法测定亚硝酸根的新方法．测定范围为２～４０ｎｇ／ｍｌ，用于肉制品和不同水样中亚硝酸根的测定。
A catalytic spectrophotometric method is proposed for determining trace amounts of nitrite. The method was based on the nitrite catalysed oxidation of brillant cresyl blue in sulphuric acid medium by potassium chlorate, with the results of decoloration. The range of determination was 2￣40 ng/ml for nitrite. The method has been used to determine trace nitrite in meat products or water with satispactory results.
