摘要
本文提出了在硫酸介质中，以锌粒还原砷产生氢化物，铁氰化钾吸收，加入高价钱沉淀，微孔滤膜过滤制成薄样，ＸＲＦ测定痕量砷的分析方法．
A method to analyzestrece amount of As is put forward in this paper. Arsenicis reduced by zinc grains in sulfuric acid to produce hydrides, absorbed by potassinm ferricyanide, precipitatsd by adding high-valent iron, filtered with porous filter membrane to form athin layer of sample, and then determined with XRF.
