摘要
The contents of environmental trace elements in permian coal from Huainancoalmine area and their combustion products were tested by ICP-MS.Analysis and comparativeresearches on the contents of eighteen environmental trace elements in coal andits combustion product suggest that Se and Cd have a high level of distribution in coals;As, Se, Cd, Sb and As, Se, Cd, Mo, Be, Sb also have a high level of distribution in 815 ℃and 1 100 ℃ coal ashes, respectively.Combustion temperature, thermodynamics featuresof trace elements and ash content in coal are the main factors that influence theabundance of trace elements in coal and ash.

Analysis and com- parative researches on the contents of eighteen environmental trace elements in coal and its combustion product suggest that Se and Cd have a high level of distribution in coals; As, Se, Cd, Sb and As, Se, Cd, Mo, Be, Sb also have a high level of distribution in 815 ℃ and 1 100 ℃ coal ashes, respectively. Combustion temperature, thermodynamics fea- tures of trace elements and ash content in coal are the main factors that influence the abundance of trace elements in coal and ash.
