中文摘要：

分别采集燃用褐煤、烟煤和无烟煤电厂排放的飞灰，研究了飞灰中碳对多环芳烃的吸附作用．研究表明：飞灰中碳含量与多环芳烃吸附量之闻具有极强的正相关性；飞灰中多孔碳与空心碳的形态结构有利于多环芳烃的吸附．研究旨在为多环芳烃的污染防治提供必要的依据．

英文摘要：

The adsorptions of polycyclic aromatic hydrocarbons with carbon in fly ash from studied. The results obtained show that there is obvious plus correlation between the adsorption power plants were capacities of polycyclic aromatic hydrocarbons and the contents of carbon in fly ash, the structure of porous carbon and hollow carbon is favorable for the adsorption of polycyclic aromatic hydrocarbons. This work could providc a possible method for the pollution prevention of polycyclic aromatic hydrocarbons.
