摘　　要：文章采用液氮破碎后微波消解的前处理方法,对矿用非金属制品进行前处理,采用电感耦合等离子体发射光谱(ICP-OES)法测定了矿用非金属制品中铅、砷、铬、镉元素的含量。该方法精密度、准确度均理想,可以满足矿用非金属制品中的重金属元素检测。In this paper,the pretreatment method of microwave digestion after liquid nitrogen crushing was used for pretreatment of mine non-metallic products.The contents of Lead,Arsenic,Chromium and Cadmium in mine non-metallic products were determined by ICPOES.The precision and accuracy of the method are ideal,which can be used to detect heavy metal elements in non-metallic products.

关 键 词：矿用非金属制品 微波消解 重金属
