- 摘要:
- 以云南4个地区不同橄榄样品为试材，经HNO3HClO4(9∶1)混合酸常压湿法消化完全后，用火焰原子吸收法测定了橄榄中Ca、Mg、Mn、Fe、Cu、Zn、Ni、Co等8种微量元素的含量。结果表明：云南4个地区橄榄中微量元素含量的高低顺序基本一致，即Mg>Ca>Fe>Mn>Zn>Cu>Co>Ni（昆明地区橄榄中Ni>Co），各元素的相对标准偏差为0.32%~4.61%，加标回收率在98.93%~103.38%；该测定方法简便、快速，所得结果准确可靠。
- Abstract:
- Taking 4 different olive varieties as test materials,the contents of eight microelements of Ca,Mg,Mn,Fe,Cu,Zn,Ni,Co of olives which were digested with mixed acid of HNO3HClO4(9∶1) by wet digestion were measured by flame atomic absorption spectrometry method.The results showed that the varieties of olive fruits purchased from four different regions in Yunnan province displayed basically identical rank order for eight microelements by content.The order of the contents of eight microelements was Mg>Ca>Fe>Mn>Zn>Cu>Co>Ni,while Ni>Co in olives of Kunmin region.The precision relative standard deviations were 0.32%~4.61%,which was based on the determination of six digests prepared.The recoveries of the results estimated in a percent average of the standard addition recoveries,were 98.93%~103.38%.The results indicated that the method was reasonable for trace analysis.
