摘要
为了研究玉溪市北城"涩水"中无机阴离子的含量是否符合《生活饮用水卫生标准》中的限值,采用离子色谱法测定了玉溪北城"涩水"中F-、Cl-、NO-3、SO2-4 的含量.结果表明,玉溪北城"涩水"中 1 月、2 月、3 月和4 月的 F-、Cl-、NO-3、SO2-4 四种无机阴离子含量低于《生活饮用水卫生标准》中的限值.该方法标准曲线相关系数在0.9990 以上,样品加标回收率在93.73%～109.20%之间,检出的数据准确可靠.结果为进一步探究"涩水"的水源保护和商用价值开发提供了数据支撑.
Abstract
In order to study whether the content of inorganic anions in"Se water"in Yuxi Beicheng drinking water meets the limit value of the national standard"Hygienic standard for drinking water",the content of F-,Cl-,NO-3 and SO2-4 in"Se water"in Yuxi Beicheng drinking season was determined by ion chromatography.The results showed that the contents of F-,Cl-,NO-3 and SO2-4 in the"Se water"in Yuxi Beicheng drinking water in January,March and April were lower than the limit value in the national standard"Hygienic standard for drinking water".The correlation coefficient of the standard curve of the method is more than0.9990,and the recovery of the sample is93.73%-109.20%,which suggested that the above data is accurate and reliable by using this method.The above results provide data support for further ex-ploring the water source protection and commercial value development of"Se water".
