摘要
采用微波消解样品、电感耦合等离子体质谱仪（ICP-MS）法同时测定笋制品中Ca、K、Mg、Al、Fe、Mn、Cu、As、Cd、Pb、Cr、Se 等12种元素。结果表明，添加回收率在86%~113%之间，相对标准偏差RSD〈5%（n=6），检出限为0.002μg/L ~2.471μg/L。4种笋制品的元素含量具有一定的差异，主要是由于笋制品的配方不同所至。该法快速简便、准确率高、精密度好，可以用于笋制品中元素的测定。
In this study, 12 kind of elements etc. Ca, K, Mg, Al1, Fe, Mn, Cu, As, Cd, Pb, Cr, Se in bamboo shoot products were determined by ICP-MS with microwave digestion. The results showed, the average recoveries were between 86% and 113%, the RSD〈5% （n=6）, the limit of determination was 0.002-2.471 μg/L. The ele- ment contents of 4 bamboo shoot products were different, due to different material contents. The method is fast, simple and accurate, could be used to determine element contents in bamboo shoot products. Key words： bamboo shoot, trace elements, ICP-MS, microwave digestion
