对煤矿矿井水各元素及其含量的测定 ,目前多采用化学法和原子吸收法。由于矿井水为酸性水 ,采用化学法一个主要的缺点就是操作繁琐 ,必须分别处理试样后 ,逐一测试。原子吸收法则由于线性范围窄 ,应用也有很大的局限性。而ICP—AES法可以做到一份试样同时测出其所含的全部元素 ,具有操作简便 ,检出限低 ,分析速度快 ,线性范围宽 ,结果准确可靠等优点 ,所以在国外已发展成为一种普遍采用的常规分析方法。就ICP—AES法同时测定煤矿矿井水中所含各元素的最佳条件的选择进行了探讨 ,并用所选取的条件进行测试 ,方法简便、快速和准确 ,结果可靠
Coal mine water elements and their determination, the current use of chemical and atomic absorption method. As the mine water is acidic water, the use of chemical one of the major drawback is the cumbersome operation, the sample must be treated separately, one by one test. Atomic absorption law due to the narrow linear range, the application also has great limitations. The ICP-AES method can be a sample at the same time to detect all the elements it contains, with simple, low detection limit, fast analysis, linear range, the results are accurate and reliable, and so has developed in foreign countries Become a commonly used method of routine analysis. The method of simultaneous determination of the optimum conditions for the determination of each element contained in coal mine water by ICP-AES method was discussed and tested with the selected conditions. The method is simple, rapid and accurate, and the result is reliable
