| Abstract: | 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. |
