摘要:

用火焰原子吸收光谱法测定海螵蛸中微量元素(Ca、Mg、K、Cu、Zn、Mn、Cr、Co、Ni、Fe、Si、Al、Pb、As 和Cd)的含量,并对结果进行分析比较。该方法的加标回收率为96.5%~108.7%,RSD 小于2.8%,具有良好的准确度和精密度。人体必需的重要微量元素Zn、Fe、Mn、Cu 含量均较高。另外,样品中还检出微量有毒元素铅、砷和镉。

关键词: 海螵蛸, 火焰原子吸收光谱法, 微量元素

Abstract:

A flame atomic absorption spectrometric (FAAS) method was developed for the simultaneous determination of 15 trace elements in cuttlebone. This method exhibited spike recoveries for 15 trace elements ranging from 96.5% to 108.7%, with RSDs of less than 2.8% and good accuracy and precision. A higher content of trace elements essential to the human body including Zn, Fe, Mn and Cu was detected in cuttlebone. Additionally, Pb, As and Cd were also detected.

Key words: cuttlebone, flame atomic absorption spectrometry (FAAS), trace elements
