采用原子荧光和化学分析方法 ,研究了渭北部分矿区石炭二叠系煤中汞的含量及汞在煤中的分布特征。结果表明 ,渭北石炭二叠系煤中汞含量较高 ,高于地壳中汞的平均含量 (0 .0 8×1 0 - 6 )及已经报导的煤和石油中汞的含量 (0 .0 0 1× 1 0 - 6～ 0 .0 3× 1 0 - 6 )。煤中汞主要以 Hg S的形式存在 ,与煤中无机硫成正比关系。同时论述了煤中汞含量与灰分等的关系。
Atomic fluorescence and chemical analysis were used to study the mercury content in coal and the distribution characteristics of mercury in coal in the Carboniferous Permian coal in part of Weibei area. The results show that the mercury content of coal in Carboniferous Permian in Weibei area is higher than the average content of mercury in the crust (0.08 × 10 ~ 6) and the content of mercury in coal and oil (0. 0 0 1 × 1 0 - 6 ~ 0 .0 3 × 10 - 6). Mercury in coal is mainly in the form of Hg S, which is directly proportional to inorganic sulfur in coal. At the same time, the relationship between mercury content and ash content in coal is discussed.
