摘要
采用微波消解方法溶样,电感耦合等离子体发射光谱法(ICP-OES)测定了铅矿中砷、镉、铜、镍、锌的含量。检出限:As、Cd、Cu、Ni及Zn等元素分别为0.0082μg/mL、0.0003μg/mL、0.0028μg/mL、0.0022μg/mL和0.0054μg/mL。回收率:93.15～101.57%。本方法的检测范围宽,对于铅精矿和铅矿砂样品都能适用,同时还具有精确度高、快速简便等优点,能满足口岸大批铅矿检验的要求。
The lead ore samples were dissolved by microwave digestion, and the As, Cd, Cu, Ni and Zn contents were determined by ICP-OES. The detection limits for As, Cd, Cu, Ni and Zn were 0. 0082 μg/mL, 0. 0003μg/mL, 0. 0028 μg/mL, 0. 0022 μg/mL and 0. 0054μg/mL, respectively. The recoveries were 93.15%-101. 57%. The method has wide measurement range and high accuracy, and is simple and rapid. It can meet the requirement for mass detection of lead ore at entry-exit ports.
