摘要
通过中子活化法 ,对淮北煤田主采煤层中和相对应的灰中几种具有环境意义的微量元素含量进行了测试 ,分析了它们在煤中和灰中的含量分布 ,并与中国和华北煤田煤中的平均值进行了对比 。
The coal samples analyzed were collected from the Huaibei coalfield and the environmental signification trace elements in the coal and ash samples were carried by Instrument Neutron Activation Analysis (INAA). The distribution of the environmental signification trace elements in the coal and ash were analyzed, and comparative study on the concentration of environmental signification trace elements between Huaibei coalfield and other Chinese coals or North china coals was conducted. The study provided reference data to use coal and ash in the future.
