中文摘要: 采用微波消解-电感耦合等离子体质谱联用技术对富硒大枣中的多种微量元素进行定量分析。该方法测得的各元素校准曲线的相关系数均大于0.998，检出限为0.006 μg/L～0.061 μg/L，相对标准偏差小于2.5%。研究表明，施硒量不同，大枣中多种微量元素呈现各自的变化趋势。随着施硒量的逐渐增加，硒对 Zn、Mn、Cu、Ca、Fe、V、Mo、Co元素的含量有明显的协同作用；而硒对重金属元素如As、Cd、Hg、Pb具有显著的拮抗作用。
Abstract:Quantitative analysis of various trace elements in Se-enriched jujube by microwave digestioninductively coupled plasma mass spectrometry.The correlation coefficients of the calibration curves measured by the method were all greater than 0.998，the detection limit was 0.006 μg/L-0.061 μg/L，and the relative standard deviation was less than 2.5%.Studies had shown that，with different amounts of selenium，various trace elements in jujube presented their own trends.With the gradual increase in the amount of selenium，selenium had a significant synergistic effect on the content of Zn，Mn，Cu，Ca，Fe，V，Mo and Co；However，selenium has a significant antagonistic effect on heavy metal elements such as As，Cd，Hg，and Pb.
