【摘要】 大量煤矸石的堆积带来一系列的环境问题。为探明煤矸石自燃对环境的有机污染效应,以太原西山杜儿坪矿的自燃矸石为研究对象,结合有机地球化学(索氏抽提、HPLC)及XRF测试等方法对样品中的有机污染物进行探究。分析结果显示,不同自燃程度的矸石含有的PAHs种类不同,未自燃矸石中PAHs的分布集中为4Ring,而燃烧煤矸石中PAHs则以低环为主。随着矸石自燃程度不断加深,矸石中PAHs总含量逐渐减低,毒性逐渐减弱。更多还原

【Abstract】 The accumulation of large amounts of coal gangue resulted in a series of environmental problems. In order to ascertain the effect of organic pollution of spontaneous combusted gangue on the environment,the spontaneous combustion of gangue in Taiyuan Xishan Duerping mine was conducted as the research object,combined with the organic geochemistry( Soxhlet extraction,high performance liquid chromatography) and XRF test method to study organic pollutants in the sample.The results revealed that gangue with different degree of spontaneous combustion contained different kinds of PAHs,and the distribution of PAHs in the no spontaneous combustion gangue was concentrated on 4 Ring,while the PAHs in spontaneous coal gangue was mainly low ring. The total content of PAHs in gangue and toxicity gradually decreased with the increasing of spontaneous combusted degree.更多还原
