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0.001～0.301μg.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。
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.
