摘　　要：在各种塑料及其制品的重金属元素测定中,对微波消解前处理的条件进行探讨。样品采用微波消解进行消化,消解后的溶液用电感耦合等离子体原子发射光谱仪(ICP-AES)进行元素检测。各种有代表性塑料样品的元素回收率及对EC680有证标准物质3次平行测定的结果显示确定的微波消解前处理条件令人满意。To discuss the pre-treatment condition of microwave digestion in the determination of heavy metals of the variety of plastics.Samples were digested by microwave digestion,digestion solution inductively coupled plasma atomic emission spectrometry（ICP-AES）for element testing.The recovery of representative samples of the various elements of plastic and certified reference materials on the EC680 3 parallel samples showed that the condition of microwave digestion in the determination of heavy metals was satisfactory.
