摘要
在现行水中亚硝酸盐氮分析方法的基础上,通过试验研究,采用便携式分光光度计建立了水体中亚硝酸盐氮的分析方法。该法与GB7493-87[N-(1-萘基)-乙二胺光度法]具有良好的可比性,分析结果的精密度和准确度均为良好,该方法可在现场简便快速测定水和废水中的亚硝酸盐氮。
On the basis of the present analytical method of nitrite nitrogen and the improred experiments were carried out, the determination method of nitrite nitrogen was developed with the use of portable speetrophotometrer. The analytical result of this method is similar to GB7493-87 [ N-（ 1-naphthyl）-ethylene diamine photometry]. This method has well aeeuvaey and precision , it can detect nitrite nitrogen in water and waste water fast simply on spot.
