Distribution of some environmental signification trace elements in coals from Huaibei coalfield

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.
