摘要
本文在查阅我国现行火焰原子吸收光谱法测定钠中铯盐用量的基础上,对《水质钾和钠的测定火焰原子吸收分光光度法》(GB 11904-1989)[1]中硝酸铯加入量进行探究,优化了硝酸铯加入量,建立上机样品中硝酸铯用量由0.60 g/L减量至0.20 g/L的新方法。应用此方法与标准方法同时测定地表水和饮用水,结果显示两种方法的测定结果没有显著差异。
We report herein an optimized amount of cesium salt need in"Water Quality-Determination of Potassium and So⁃dium-Flame Atomic Absorption Spectrophotometry"(GB 11904-1989)[1]to establish a new method with the decreased amount of cesium nitrate in samples from 0.60 g/L to 0.20 g/L.Comparing to the standard method,this method showed equal accuracy to measure either surface or drinking water.
