摘　　要：采用(盐酸+硝酸+氢氟酸)微波消解溶解进口铁矿,然后利用氢化物发生原子吸收法测定样品中的砷。本方法检出限低、线性范围宽,能够满足铁矿石的分析要求。Imported iron ores were digested by microwave using （ HCl ＋ HNO3 ＋ HF）, The content of Arsenic in iron ores were determined using HG-AAS. The method gave low determination limit and wider linear area. It was satisfied the demand of iron ores analysis.

关 键 词：微波消解 氢化物发生原子吸收法 进口铁矿 砷
