摘要
亚硝酸盐氮是生活饮用水、地下水质量标准中重要的检测指标,水中亚硝酸盐氮的含量事关人体健康。因此,对水质亚硝酸盐氮的准确检测是十分必要的。目前,国内外普遍使用的检测方法有3种:分光光度法、离子色谱法、气相分子吸收光谱法,本文以此为基础,分析比较这三种方法,以便遇到不同水质时,能快速选择适合、高效、精确的检测方法,提高实验室的检测效率及能力。
Nitrite nitrogen(NO2-N)is an important detection index in the quality standards of drinking water and groundwater.The content of NO2-N in water is closely related to human health.Therefore,the accurate detection of NO2-N in water is very necessary.At present,three detection methods have been widely used,including spectrophotometry,ion chromatography and gas phase molecular absorption spectrometry.On this basis,this paper make a comparation of the three methods for the precise selection when different water quality is encountered.It will help to improve the detection efficiency and capabilities in the laboratory.
