引言本文主要研究以为还原剂,利用盐酸溶液为载体溶液,运用氢化—原子荧光方法来检测水中的砷、汞、硒元素。检出限小于检测标准要求;相对标准偏差都均小于5%;标准样品实验后的结果显示,所有实验结果都符合标准要求;通过对加标回率的观察,可以很好的说明了运用氢化—原子荧光方法来测定水中的砷、汞、硒,具有很好的应用效果,此种方法有非常高的准确度、方法比较简单等一些优点。氢化—原子荧光方法测定技术在很大程度能够对几种不同的
In this paper, the main study that reductant, the use of hydrochloric acid solution as the carrier solution, the use of hydrogenation - atomic fluorescence method to detect water arsenic, mercury, selenium. The detection limit is less than the test standard requirements; the relative standard deviations are less than 5%; the results of the standard sample experiments show that all the experimental results are in line with standard requirements; Through the observation of the spike recovery rate, can be a good illustration of the use of hydrogenation - Atomic fluorescence method for the determination of arsenic, mercury, selenium in water has a good application effect, this method has a very high accuracy, the method is relatively simple and some other advantages. Hydrogenation - atomic fluorescence spectrometry techniques are largely capable of several different
