摘　　要：首次采用浸提试验系统研究煤中氟化物赋存形态。结果表明,许多溶剂都能从煤中浸出相应形态和数量的氟化物,煤中不同浸提态氟按氟含量高低存在如下趋势:酸浸提态氟>碱浸提态氟>盐浸提态氟>水浸提态氟,浸提结果反映了煤中几种不同赋存形态氟化物含量的数量级概念,以无机盐矿物形态存在的难溶性氟化物是煤中氟的主要赋存形态。研究结果可为煤中氟赋存形态的研究提供试验方法与依据。The occurrence modes of fluorine in coal have been systemically researched by means of extracting experiment method for the first time. The research results have showed that the different occurrence modes and quantity of fluorine in coal can be extracted by different solvents, and the sequence of extracting ability of different solvents is as follows: acid extractable fluoride> alkaline extractable fluoride>salt extractable fluoride>water extractable fluoride, extracting results reflect the fluoride quantity grade of different occurrence modes of fluorine in coal, and the fluoride may be the main fluorine-bearing minerals in coal .The research results can provide the experiment method and data for the occurrence modes of fluorine in coal.
