中文摘要: 水质中硫酸盐的测定方法很多,但对于成分复杂且盐分很高的矿山水样,传统方法操作繁琐且不环保,本文建立了等离子体发射光谱法测定矿山水样中硫酸盐的方法,样品采用硝酸和盐酸进行加热消解后既可去除硫化物,降低水质的黏度,又可实现多元素同时测定。该方法检出限为0.03mg/L,相对标准偏差为0.1~0.4%(n=6),方法具有方便,快捷,检出限低,精密度、准确度高且线性范围广的优点。
Abstract:Many methods for the determination of sulfate in water. However, the traditional methods is tedious and not environmentally friendly for complex and high salinity water samples around mine. In this paper, a method was established to determinate the sulfate in mine water samples. The sample is heated by adding HNO3 and HCl can not only remove sulfide , but also realize simultaneous determination of multiple elements. The detection limit of the method is 0.03, the relative standard deviation is 0.1~0.4%(n=6). The method has the advantages of convenience, fast, low detection limit, high accuracy and wide linear range.
