采用微波消解法处理地笋样品,电感耦合等离子体发射光谱(ICP-AES)测定其中K、Na、Ca、Mg、P、Sr、Fe、Mn、Zn、Cu、Co、Cr、Al、Ba、Ni、As、Pb和Cd 18种常量和微量元素的含量。18种元素的检出限为0.00003～0.00990μg/mL,回收率89.20%～110.00%,相对标准偏差(RSD)均小4.8%。结果显示,地笋样品中除含有人体必需的常量元素K、Na、Mg、Ca外,还含有Fe、Zn、Mn、Cr、Co等必需的微量元素和其他元素P、Ni、Ba、Al、Sr、Pb、Cd、Ba等。 The contents of K, Na, Ca, Mg, P, Sr, Fe, Mn, Zn, Cu, Co, Cr, Al, Ba and Zn in the shoots were determined by microwave digestion method and inductively coupled plasma atomic emission spectrometry (ICP- Ni, As, Pb and Cd 18 kinds of constants and trace elements content. The detection limits of the 18 elements ranged from 0.00003 to 0.00990 μg / mL and the recoveries ranged from 89.20% to 110.00% with relative standard deviations (RSDs) of 4.8%. The results showed that in addition to the K, Na, Mg and Ca, which are essential for human body, the samples of ground shoots contain the trace elements such as Fe, Zn, Mn, Cr, Co and other elements such as P, Ni, Ba, Al, Sr, Pb, Cd, Ba and the like.
