摘要
对长城窝堡井田煤中砷的含量和赋存状态的研究得出:研究区煤中砷含量较高,算术平均含量高达95.5m g/kg,远高于中国煤中砷的含量;砷与灰分之间关系不明显,砷主要赋存在以黄铁矿为主的硫化物中,有机硫是导致煤中有机结合态砷存在的一个因素。
Investigation of arsenic content and occurrence in coal of Changchengwobao mine coalfield showed that arsenic content is big, and its arithmetic average content reaches 95. 5 mg/kg, which is much bigger than in coal of other coalfields in China. Arsenic content is relevant to ash content unnoticeably. Pyrites are the main carriers of arsenic occurrence in coal, and organic sulfur occurrence is one of reasons resulting in arsenic occurrence in coal.
