摘要： 采用不同吸附剂对煤烟气中的痕量有机物进行了富集,比较了各种吸附剂的富集能力,对富集的样品用索氏提取及超临界流体萃取装置进行了萃取,用GC－MS,DS联用方法作了定性鉴定,指出超临界萃取技术在提取煤烟气中痕量有机物方面的优势.探讨了用催化转化法去除煤烟气中有机污染物的可能性.

关键词: 煤烟气, 痕量有机物, 富集, 超临界流体萃取

Abstract: An analysis system of trace organic compounds in smoke from burning coal was established, which included concentration of organic compounds by adsorbent, super critical fluid extraction (SFE), and gas chromatography-mass spectroscopy for identification.The abilities of four kinds of adsorbents were compared.SFEis superior to solvent extraction in extracting organic compound in coal smoke, More than 130 compounds were detected, in-cluding alkane, alkene, aromatic hydrocarbon with low ring number, alcohol, aldehyde, ke-tone, acid, ester, phenol, polyring compounds and heterocyclic compounds.The possibility of elimination organic compounds by using catalyst of CuO-Mn/Al2O3 was researched for the first time.It was shown that thls kind of catalyst can eliminate most of the organic contami-nats in smoke effectively and economically.
