摘要
提出了催化分光光度法测定水中痕量亚硝酸盐氮的新方法，并对含量范围０．１０μｇ／ Ｌ～１．００μｇ／ Ｌ 进行了测定．研究结果表明，在此线性范围内，样品变异系数为 ３．６％ ～４．５％ ；回收率为９７．０％ ～１０７．０％ ．
It provides a new method of determining the content of nitrogen f trace nitrous acid salt in aqueous system with catalylic spectrophotomety,and determining the content from 0.10 μg/L to 1.00μg/L.The result suggests that within this linearity bounds the coefficient of variation is from 3.6% to 4.5% and reclamation efficiency from 97.0% to 107.0%,thus it has better fineness and percent of accuracy.
