摘　　要：采用微波消解制样技术,用电感耦合等离子体发射光谱(ICP-AES)法测定聚氯乙烯(PVC)塑钢门窗中的Pb、Zn、Ti、Cu等重金属元素含量,确定了实验的最佳测定条件。结果表明:方法的检出限为0.01840～1.034μg/mL,回收率为94.23%～103.5%,相对标准偏差在4.6%以内。该方法灵敏度高、准确、快速,可满足PVC塑钢门窗中金属元素的常规测定。Inductively Coupled Plasma-Atomic Emission Spectrometry （ICP-AES） method was used to determine heary metal elements such as Pb,Zn,Ti and Cu in PVC plastic-steel door and window based on microwave digestion samplemaking technique. The optimum determination condition was obtained. The results showed that the sensitivity of the detection limit was 0. 01840 - 1. 034 μg/mL,the RSD was less than 4. 6 % and the recovery was from 94.23 % to 103.5 %. This method was accurate,quick and could meet the coventional determining of metal elements in PVC plastic-steel door and window.
