摘　　要：建立了同时测定机电产品中10种金属元素含量的全谱直读电感耦合等离子体发射光谱法（ICP-OES）。通过优化仪器分析条件,采用各元素特征波长谱线定性,外标法以特征谱线强度进行定量。方法对不同金属元素的测定限（LOQ）在0.1～40mg/kg之间,回收率为89%～105%,相对标准偏差在0.95%～4.02%之间。方法简便、准确、灵敏、快速,回收率高、精密度好。Ten metal elements in electronic and mechanical products were determined simultaneously by ICP-OES.The analysis condition was critically optimized in this study.The LOQ of ten metal elements were between 0.1 to 40 mg/kg.The relative standard deviations（RSD） were 0.95%～4.02%,and the recoveries were 89%～105%.The testing results show that the procedure is simple,accurate,rapid with good recoveries and precision.
