摘　　要：采用HNO3-H2O2微波溶样、电感耦合等离子体质谱法测定了鹿骨粉中的微量元素.在优化的实验条件下,方法的检出限（3σ,n=11）为0.0006～1.498 ng·mL^-1;标准加入回收率为91%～109%,相对标准偏差为1.7%～6.8%.对国家标准物质样品分析的结果与所给参考值吻合.Contents of trace elements in sika bone powder were determined with microwave digestion and inductively coupled plasma mass spectrometry. Under the optimum conditions, the detection limits （3σ, n= 11） are in the range of 0. 000 6-1. 498 ng ·mL^-1 with relative standard deviations of 1.7%-6. 8%. The recoveries are between 91% and 109%. The analytical results of national certified reference demonstrated the applicability of the proposed method.
