摘要
本文采用利凡诺为显色剂，比色测定苯扎溴铵消毒液中亚硝酸钠的含量，方法简便，结果较好。线性范围２０～４５μｇ／ｍｌ，ｒ＝０．９９９９，回收率为９９．２７％（ｎ＝５），ＲＳＤ＝０．３９％。
The paper reported determination of content of sodium nitrite in bromogeramine solution for disinfection with colorimetric method in rivanol as developer. This method was simple and result was good. The linear range was 20～45μg/ml.r=0.9999 Average rocovery was 99.27%(n=5),RSD=0.39%
