青山烟煤及其燃后飞灰中有机污染物分布的研究

采用色谱／质谱联用系统对青山烟煤及其燃烧产物－飞灰７Ｈ，１６Ｈ和２４Ｈ二氯甲烷索氏抽提液中脂肪烃、苯系物及多环芳烃等有机污染物的种类和含量进行了测量，得到了青山烟煤及其飞灰产物中有机污染物的分布特征。

An Investigation of the Distribution of Organic Pollutants from Qingshan Bituminous Coal and its Post combustion Fly Ash

With the help of a GC/MDS system determined from the extractive solutions of 7 hours,16 hours and 24 hours the sort and content of such a variety of organic pollutants as aliphatic chains,benzene families and polycyclic aromatic hydrocarbons(PAHs),and obtained are the distribution characteristics of the organic pollutants of Qingshan bituminous coal and its fly ash products The test results show that there are several kinds of organic pollutants,especially PAHs,in the raw coal itself The different sorts and content of benzene families in the fly ash will increase while those of the PAHs decrease following the combustion of the raw coal The rational organization of the combustion process can play a significant role in achieving a decrease in organic pollutants
