    Study on Modes of Occurrence of Mercury in Coals from the Huaibei Coalfield

    • 摘要: 系统采集淮北煤田10、7、5、4和3煤层的29个煤样品, 采用逐级化学提取方法研究了煤中汞的赋存状态, 根据提取步骤和汞的特性, 将煤中的汞分为水溶态、离子交换态、有机态、碳酸盐结合态、硅酸盐结合态和硫化物结合态, 利用Flow Injection Mercury System(FIMS)分析了样品中总汞和不同形态中汞的含量.测试结果表明, 与华北石炭-二叠纪煤、中国煤以及美国煤含量相比较, 淮北煤田煤中汞的含量明显富集.逐级化学提取实验结果和煤中汞与硫、灰分的相关分析结果表明, 岩浆的侵入对煤中汞的赋存状态有较大的影响, 不受岩浆侵入影响的10、4和3煤层煤中的汞主要以有机态和硫化物结合态存在, 受岩浆侵入影响的5和7煤层中的汞主要以硅酸盐结合态存在.
