Abstract
Using microwave digestion to process raw coal samples, and applying inductively coupled plasma mass spectrometry (ICP-MS) method, we determined the content of 12 trace elements (Cr, Mn, Ni, As, Cd, Mo, Hg, Th, Sb, Pb, Se) in Shanxi and Henan coals. Content level and distribution characteristics of trace elements in coals were studied, and enrichment mechanism was explored. The result showed that content of trace elements in coal appeared dramatically unhomogeneous, the content of some elements was high, especially these recognized toxic elements like Cd, Pb, Se, and Hg significantly enriched. Element content in coal was correlated to coal-forming environments.关键词
