摘要
氟是煤中所含微量元素中丰度较高的少数几种元素之一。对我国581个煤样分析数据的统计表明，多数样品氟含量片地20－300mg/kg，平均40mg/kg，个别超过1000mg/kg。氟在煤中赋存状态有：（1）独立的氟矿物；（2）以类质同象存在于矿物晶格内；（3）被矿物吸附；（4）以F^-离子形式溶于水中，在煤中所含微量元素中，氟是对植物、动物和人体健康的影响面最大的元素。
Among the trace elements in coal fluorine is one of the higher conten t elements.Based on the systematic collections of 581 coal samples in China ,mo st of the F contents of coal in China range between 20mg/kg and 300mg/kg and the average value is about 40mg /kg ,few is above 1000 mg /kg.The modes of F occur rence in coal are:F-mineral alone;isomorphic substituting in mineral lattices ;being absorbed by other minerals;F-ionic dissolved in water.Among the trace elements in coal F affects on the health of plant,animal and people most exten sively.
