| 摘 要： | 沙棘果油样品经微波消解处理，采用电感耦合等离子体质谱法测定所得样品溶液中铁、硒、锌、钾、钠、钙、镁、铜、锰、铅、砷、汞、镉等13种微量元素的含量。使用动态反应池技术消除了多原子离子对部分被测元素的干扰。方法快速准确、灵敏度高，加标回收率在96.1%～101%之间，相对标准偏差小于3%。

| Abstract: | The sample of Seabuckthorn fruit oil was treated by microwave assisted digestion, and the contents of Fe,Se,Zn,K,Na,Ca,Mg,Cu,Mn,Pb,As,Hg and Cd in the sample solution were determined by ICP-MS, The polyatomicions interference on the part of the measured elements were eliminated by the technique of dynamic reaction pool. This method was simple,rapid,nicety,and sensitive. Recover-ies were in the range of 95.5%~102.8%,and the RSD was less than 3%. |
