高钙碳酸盐地质样品中铜镍的测定

Determination of Copper and Nickel in High-calcium CarbonateGeological Samples

摘要: 用电感耦合等离子体质谱法和电感耦合等离子体发射光谱法测定高钙碳酸盐样品中的铜和镍。通过试验分析了高钙碳酸盐样品中钙对铜、镍测定的影响，并确定其影响因子，提出两套检测高钙碳酸盐样品中铜、镍的方案。方法经国家标准物质验证，测定值与标准值相符；相对标准偏差（RSD，n＝10）两元素均小于2%。

Abstract: In this work, the analysis of copper and nickel in highcalcium geological samples was carried out with inductively coupled plasma-mass spectrometry (ICP-MS) and inductively coupled plasmaatomic emission spectrometry (ICPAES). The results indicated that calcium interfered with the determination of copper and nickel. Through the experiments, the interference factors were determined and applied to interference correction. The method has been tested by determination of copper and nickel in geological standard reference materials and the results are in good agreement with certified values with precision of <2%RSD (n=10).
