摘　　要：通过优化分析条件,实验研究了微波消解前处理和电感耦合等离子体发射光谱（ICP-OES）联用法（MAE-ICP）测定合成树脂瓦中的Pb、Cd、Cr、Hg、Ba和Zn等6种重金属的含量.方法的线性相关系数大于0.999,检出限为0.0012-0.0220 mg/L,回收率在96.8％-103.1％,RSD小于4.6％.该方法灵敏度高、重复性好,可实现对合成树脂瓦中重金属的含量快速准确地测定.Microwave digestion pretreatment and inductively coupled plasma-optical emission spectrometry （ICP-OES） joint techniques（MAE-ICP） was used to determine heavy metal contents such as Pb,Cd,Cr,Hg,Ba and Zn in synthetic resin tile. The optimum determination condition was obtained. The linearly dependent coefficient were all greater than 0. 999, the detection limit was 0. 0012 - 0. 0220 mg/L,the recovery was from 96.8 % to 103.1% and the RSD was less than 4.6 %. The method was high sensitivity, good reproducibility, could rapidly and accurately determinate the content of heavy metals in synthetic resin tile.
