Sulfur in Coal and Its Environmental Impact from Yanzhou Mining District, China
摘要
Abstract
Sulfur is one of the hazardous elements in coal. The concentrations of sulfur are rela tively high in coal. The major forms of sulfur in coal are pyritic, organic and sulfate. Pyritic and organic sulfur generally account for the bulk of sulfur in coal. Elemental sulfur also occurs in coal, but only in trace to minor amounts. When coals are burned, leached and washed, sul fur will be released in the form of sulfide and H2S, which then react with O2, waterand other substances to change into vitriol, and in some places it may form acid rain. And they will im pact water environment, acidify the soil and do great harm to plants and human health. In this paper, on the basis of the data from the Yanzhou mining district, the distribution and concen trations of sulfur are analyzed and the existing forms of sulfur are studied. The variation of sul fur and its impact on the environments also are described when coal is used.关键词
