首次报道了鳄梨中微量元素的含量分析方法。采用HNO3－H2 O2混合酸，经微波消解进行样品前处理，电感耦合等离子体光谱（ ICP－OES）和电感耦合等离子体质谱法（ ICP－MS）测定其中B等22种微量元素。该方法简便、快速，各元素测定的相对标准偏差小于5％（RSD， n＝7），样品加标回收率在90％～110％之间，用于国家一级标准物质胡萝卜（GBW10047）分析，结果满意。

A method for determination of trace elements in avocado was reported first time.22 elements such as boron were determined by ICP-OES and ICP-MS with microwave digestion and HNO 3-H2 O2 mixed acid.This method was simple and rapid for use.The RSDs ( n=7 ) for every element were all less than 5% and recoveries were among 90%~110%.The analytical results for Certified Reference Material ( GBW 10047 ) were approving.
