焦炉烟气中全量多环芳烃分析方法

Analysis of the Total Polynuclear Aromatic Hydrocarbons in Coke Oven Smoke

报道了利用自制串联采样装置，优选出了比较理想的前处理方法，并用此方法对焦 炉烟气中的全量多环芳烃进行了研究。滤膜颗粒物中的多环芳烃有６２种，聚氨酯泡沫吸附剂 （水气）中有４９种。颗粒物中多环芳烃的含量大部分高于空气中的多环芳烃含量，其它吸附剂 及吸附液中，除 ＧＤＸ－１０２中仅有萘、菲、蒽 ３种多环芳烃以外，其它均无多环芳烃出现。

In this paper, a new method of sample pre-treatment was developed using a series connection sampling set. In the coke oven smoke samples 62 kinds of PAH absorbed by filter film and 49 kinds PAH by ployurethane foam absorbents were determined by GC and GC/MS. The content of PAH in filter film is higher than that in air. Among other ab- sorbents only 3 kinds of PAH (naphthalene, phenanthrene, anthracene) were detected in GDX-102.
