【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0·0006~1·498ng·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。更多还原

【Abstract】 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.更多还原
