摘要:

利用微波消解-电感耦合等离子体质谱(ICP-MS)法测定苦竹等20种竹叶中18种无机元素。该方法检测限为0.001~0.301 μg·g-1,各元素的相对标准偏差为2.19%~7.30%,元素的回收率为80.7%~122.4%。该方法简单、快速、灵敏、准确,适用于竹叶中多种元素同时测定。竹叶中富含K,Ca,Mg,Fe,Al,Mn等元素。

Abstract:

A method combining on microwave sample digestion and inductively coupled plasma-mass spectrometry (ICP-MS) detection was established for determining of multiply inorganic elements in Bamboo leaves. Determination limits of 19 elements were in a range of 0.001~0.30 μg·g-1, coefficients of variation (CV) were in a range of 2.19%~7.30%, and the recoveries of elements were in a range of 80.7%~122.4%. The results indicated that the method is simple, rapid, sensitive and accurate, and can meet the demand for 18 elements analysis in bamboo leaves. Ca, Mg, Fe, Al, Mn is relative abundant in the bamboo leaves.

Key words: bamboo leaves, elements, ICP-MS, microwave digestion
