摘要
采用高温热水解离子选择性电极(ISE)测试了重庆南桐煤田南桐煤矿5#煤层和东林煤矿4#和6#煤层煤中氟,并通过统计分析初步推断了其赋存状态。结果表明:重庆南桐煤田煤中氟的平均含量明显高于重庆及全国的氟的含量水平;无机亲和性弱,可能主要赋存于有机物中。
Content of Fluorine have been studied in groove samples collected at No.4 and No.6 coal seams in Donglin and No.5 coal seam in Nantong, Chongqing by pyrohydrolysis in conjunction with a fluoride ion-selective electrode. Concluded the occurrence mode of Fluorine through statistical analysis.The result showed that the average Fluorine concentration in Nantong coalfield is higher than Chongqing and the world.Fluorine in coal has feeble sulphophile affinity and inorganic affinity. Organic Fluorine is dominating in occurrence modes of fluorine in coal.
