摘　　要：在氯酸钾作氧化剂的条件下用浓硝酸将硫或碳氧化成硫酸或二氧化碳,用王水在沸水浴中溶解多种矿石样品中的砷,用火焰原子吸收光谱法测定。方法检出限为0.0032%,精密度为1.60%—3.65%。Sulfur or carbon was oxidized to sulfuric acid or carbon dioxide by concentrated nitric with condition of potassium chlorate as oxidant,and arsenic in the kinds of ores samples was dissolved by aqua regia in a boiling water bath,then was determined by flame atomic absorption spectrometry（FAAS）.The detection limit was 0.0032 %,and the precision was in the range of 1.60%—3.65%.
