摘  要:
本文叙述应用ICP-MS法同时测定食品中9种人体必需微量过渡元素(V、Cr、Mn、Fe、Co、Ni、Cu、Zn和Mo)的测定方法。采用以Rh作内标的外部校正形式。用微波消解样品。对照分析了参考标准物质。对于所有元素,校正曲线的相关系数为0.9990,回收率范围为90.2%~106%,相对标准偏差0.4%~4.4%(n=11)。

摘  要:
Inductively coupled plasma mass spectrometry was employed to simultaneous detertmine 9 trace necessarytransitional elements(V、Cr、Mn、Fe、Co、Ni、Cu、Zn and Mo)for human in foods. Calibration with rhodium asthe internal standard was used .The samples were digested using a microwave oven. The results of the analysis of reference materialwere compared with certfied values.For all analyte elements,the correlation coefficient of the calibration curves was 0.9990,therecoveries in the 90.2%~106% range,the relative standard in the 0.4%~4.4% range.
