摘　　要：建立了用电感耦合等离子体光谱法 (ICP-AES)和高效液相色谱法 (HPLC)分别测定焚烧炉烟气中铅(Pb)、锌 (Zn)和苯并 (a)芘 (Ba P)的分析方法。研究了烟尘及玻璃纤维滤筒的预处理 ,测定 Pb、Zn、Ba P时基体的干扰与消除 ,并给出 Pb、Zn的干扰校正系数。实验测得 Pb、Zn和 Ba P的回收率超过 84% ,相对标准偏差 Pb为3 .5 1 % ,Zn为 7.2 8% ,Ba P为 4.3 0 %。实验结果表明 。An analitical method was developed for the determination of lead(Pb),zinc(Zn) and benzo(a)pyrene (BaP) in flue gas of radwaste pyroysis incinerator, respectively using Inductively Coupled Plasma-Atomic Emission Spectrometry(ICP-AES) and High Performance Liquid Chromatography(HPLC).The sample preparation and the influence of major components in background were researched. Interference correction coefficient for Pb and Zn are given in this article. The recovery of Pb, Zn and BaP are all above 84.0% and the relative standard deviation(RSD) were 3.51% for Pb, 7.28% for Zn and 4.50% for BaP,respectively.It shows that this analytical method can meet the incineration processes.
