摘　　要：基于亚硝酸根在醋酸介质中对氯酸钾氧化耐尔蓝褪色反应的催化作用,建立了测定痕量亚硝酸根的催化光度新方法.测定亚硝酸根的线性范围为0～0.3 mg/L,检出限为0.0nA new catalytic spectrophotometric method for determination of trace nitrite has been developed. It is based on the catalysis of nitrite to the discoloring reaction of nile blue sulphate oxidized by potassium chlorate in acetic acid dium. There was lineat relationshop of AA with nitrite in the range 0?0. 3 mg/L. The detection limit was 0. 011mg/L.
