摘要
煤中微量元素是世界洁净煤研究的热点 ;煤中微量元素的研究对于正确评价微量元素 ,预防煤中有毒有害元素对环境的影响 ,保护生态和人类生存的环境具有重要的理论指导意义和现实意义。本文详细介绍了国内外煤中微量元素的研究进展 ,微量元素的分布规律、赋存状态及研究方法 ,并将其研究内容概括为基础理论研究和应用研究两个方面 ,详细介绍了研究方法 (直接方法和间接方法 ) 。
The study of trace elements was focus of clean coal technology in the world. In this paper, the great significance of studying trace elements in coals was expounded. It is reported that the study of trace elements was very important to evaluate trace elements, to prevent environment from pollution by hazardous elements and protect ecosystem and living conditions. The new advance in researches of trace elements in coals was minutely introduced at home and abroad, and the occurrence state of trace elements was analyzed and the research methods of trace elements were discussed which included direct methods and indirect methods. Furthermore, the major research directions of trace elements in the future were mentioned.
