英文摘要为解决电感耦合等离子体质谱仪(ICP-MS)测定蜂王浆中硒(Se)含量时产生的干扰问题,应用动态反应池(DRC)技术,通过对反应气种类、流量及测定元素同位素的优化,确定了消除干扰的方法。实验结果表明,当以~(78)Se为分析物,甲烷(CH_4)为反应气且流量为0.5 mL·min~(-1)时,可有效降低干扰。该方法的线性范围宽(0.1 ~ 100 μg·L~(-1)), 检出限低(0.052 2 μg·L~(-1)), 精密度好,重复测定7次结果的相对标准偏差(RSD)均小于5%,加标回收率为95.0%~ 103.9%。实际样品测定结果显示,DRC-ICP-MS法与经典原子荧光法的测定结果相比无显著差异。; To eliminate the interference on the determination of selenium(Se) in royal jelly by inductively coupled plasma mass spectrometry(ICP-MS), a dynamic reaction cell(DRC) method was established by the study of reaction gas species,flow rate and isotope of Se. The results showed that ~(78)Se was suitable for the analysis. The interference on the determination of Se was eliminated when CH_4 was used as reaction gas and its flow rate was set to 0.5 mL·min~(-1). The method had a wide linear range of 0.1-100 μg·L~(-1) and a low detection limit of 0.052 2 μg·L~(-1). The relative standard deviations(RSD) were less than 5%. The recoveries were between 95.0% and 103.9%. The differences of the results of Se in royal jelly samples determined by DRC-ICP-MS and atomic fluorescence spectrometry were not significant.
