摘　　要：采用盐酸、硝酸、高氯酸、氢氟酸分解样品,确定仪器测量条件,使用国家标准物质绘制标准工作曲线,用电感耦合等离子体发射光谱法测定多金属矿中的铜铅锌含量。实验结果表明,该方法与使用国家标准溶液绘制标准工作曲线相比,样品含量检测范围更宽,具有更好的精密度和准确性。Samples were decomposed using hydrochloric acid,nitric acid,perchloric acid,and hydrofluoric acid to determine instrument measurement conditions.Standard working curves were drawn using national standard materials,and the copper,lead,and zinc contents in polymetallic ores were determined using inductively coupled plasma emission spectroscopy.The experimental results show that compared with using national standard solutions to draw standard working curves,this method has a wider range of sample content detection and better precision and accuracy.
