摘要
基于前人资料的分析总结,系统探讨了煤中Ag等26种有害微量元素的赋存状态。研究结果表明:煤中有害元素或多或少都与无机质、有机质有联系,只是联系程度不同。有些在地壳中被认为彼此关系不大的元素,在煤中却密切相关。煤中B、Be、Br等主要以有机相赋存,其它有害元素主要与矿物质有关。
Based on the analysis and summation of previous publications,modes of occurrence of Ag and other 25 hazardous trace elements in coal were systematically discussed.The results showed that the hazardous trace elements in coal are more or ress associated with inorganic and organic matter but in different association degree.Some element which were thought to show unclose relation in the crust were found to have close interrelation in coal. B, Be and Br in coal show stronger affinities to organic matter, but the other hazardous trace elements in coal are mainly associated with minerals.
