摘要
研究了用率磷酸盐滴定法分解样品，用散射线内标法克服基体效应影响，在硫酸溶液介质中，采用Ｘ射线荧光光谱法则定矿石中０．５％～３５％的砷，取得了较满意的结果。
The decomposition of specimen with hypophosphite titration,re-moval of the influence of matrix effect with scattering radiation internal stan。dard method are discussed in this paper,In sulphuric acid solution,0.5%～35%As in ore meassured with X-ray fluorescene spectrography can be success.fully obtained.
