摘要

目的: 建立了冰硼散中硼、汞的含量测定方法。方法: 电感耦合等离子体质谱法(ICP-MS)

样品经微波消解

以铋(Bi)、铍(Be)为在线内标

调节仪器测定参数

确定仪器最佳工作条件;配制各元素系列标准溶液

将试剂空白、标准系列、样品溶液分别引入仪器同时测定;加样回收率试验验证方法的准确度。结果: 汞在0~60 μg ·L-1线性关系良好

平均回收率 99.7%;硼在0~80 μg ·L-1线性关系良好

平均回收率99.4%。结论: 研究所建立的方法具有简便、快速、准确、灵敏度高的优点

可用于冰硼散的质量控制。

Abstract

Objective: To establish a method for the determination of boron and mercury in Bingpengsan. Method: The samples were digested by microwave. Boron and mercury in Bingpengsan were directly analyzed by ICP-MS. Bi and Be were selected as the internal standard

and the instrument parameters were adjusted to the optimum working conditions. Serial standard solutions were prepared. The reagent blank

standard series and the sample solutions were added to equipment and detected. The accuracy of the method was validated by recovery rate. Result: Mercury was linear in the range of 0-60 μg ·L-1; the average recovery was 99.7%. Boron was linear in the range of 0-80 μg ·L-1; the average recovery was 99.4%. Conclusion: This method is convenient

quick

accurate and highly sensitive. The method can be used for the quality control of Bingpengsan.
