摘要
[Objective] This study was conducted to investigate the Mg level in cray- fish. [Method] Microwave digestion was applied to treat crayfish sample, Mg content in which was then determined by flame atomic absorption spectrometry, and recov- ery test and the determination of standards were also performed. [Result] This method was used for the detection of Mg in crayfish, obtaining satisfactory effect. The sample recoveries were in the range of 90.0%-110%, and the detection limit was 0.8 mg/kg. [Conclusion] The method is rapid, simple, accurate and reliable, worth extending.
[目的]测定小龙虾中镁的含量水平。[方法]利用微波高压消解技术对小龙虾样品进行了试验,采用火焰原子吸收法进行测定,并通过加标回收试验及对标准物质进行测定。[结果]使用微波消解-原子吸收法检测小龙虾中的镁,样品回收率在90.0%~110%,检出限为0.8mg/kg。[结论]该方法快速准确、可靠,值得推广。
