| 摘 要： | 用逐级化学提取方法，分析了煤中有机质结构的合的微量元素含量与煤级关系。结果表明，有机态结合的微量元素在褐煤中含量比较高。烟烟中含量降低，到无烟煤阶段，有机态微量元素含量进一步降低，证明了随煤化程度增加，煤中有面态的微量元素含量降低。

| Abstract: | For investigating the relationship between the organic affinity of trace elements and the rank of coal,the sequential extraction procedures for 12 coal samples have been carried out.The result show that the organic affinity of trace elements in brown coal is higher.In bituminous coal,the organic affinity of trace elements decreases.The organic affinity of trace elements decreases further in anthracite.It seems reasonable to assume that the organic affinity of trace elements decreases with the coal rank increasing. |
