电感耦合等离子体发射光谱法测定钼矿石中钴铬铜钼镍铅锡钨钇锌

Determination of Co, Cr, Cu, Mo, Ni, Pb, Sn, W, Y and Zn in Molybdenum Ores by Inductively Coupled Plasma-Atomic Emission Specrometry

摘要: 采用盐酸-硝酸-氢氟酸-高氯酸-柠檬酸处理样品，电感耦合等离子体发射光谱法同时测定钼矿中钴、铬、铜、钼、镍、铅、锡、钨、钇、锌10个元素，筛选了不同溶矿方法和仪器参数条件。测定的相对标准偏差（RSD,n=11）均小于3.0%，经国家一级钼矿标准物质分析验证，结果与推荐值吻合。

Abstract: The quantitative analysis of 10 elements including Co, Cr, Cu, Mo, Ni, Pb, Sn, W, Y and Zn in molybdenum ores by inductively coupled plasmaatomic emission spectrometry (ICP-AES) with mixed acid sample pretreatment was performed. The sample pretreatment parameters and instrument operation condition were optimized. The method has been verified by determination of these components in molybdenum ore National Standard Reference Materials and the results are in agreement with certified values with precision of less than 3.0%RSD
