Using ICP-AES inductively coupled plasma emission spectrometer to determine the seven kinds of Cu, Pb, Zn, W, Mo, Co, Ni and other elements in the polymetallic ore samples, and with a satisfactory result. The detection limit is 0.001 5~ 0.006 1 μ g/mL, the precision is 0.61-2.75, and with the national standard reference material to verify the measured value and the standard value, indicating that the metal in the ICP method for the determination of metal ores the element has a small interference, a good precision, a wide range of linear analysis and can be multi-element simultaneous determination. It can be applied to determine the polymetallic ore samples.%文章采用ICP-AES电感耦合等离子发射光谱仪,对多金属矿样品中铜、铅、锌、钨、钼、钴、镍等7种元素进行了测定,取得了满意的结果.方法检出限为0.001 5～0.006 1μg/mL,精密度为0.61～2.75,经国家标准物质验证,测定值和标准值一致,表明ICP法测定多金属矿中的金属元素具有干扰小、精密度好、线性分析范围宽和可多元素同时测定等优点,可以适用于多金属含量的测定.
