摘要
煤中微量元素的赋存状态和成因机理可为研究煤层的形成提供重要的地球化学依据。逐级化学提取(SCEP)方法常用于煤中微量元素赋存状态的定性或定量研究。SCEP早期主要被应用于煤中有害微量元素的研究,近期开展了有益微量元素在煤中存在形式的探究工作,对煤中锂的研究尚处于起始阶段。综述了SCEP技术在煤中有害和有益微量元素赋存状态方面的应用进展,对煤中不同赋存状态的微量元素进行了分类总结,提出利用逐级化学提取法研究煤中锂的赋存状态,为煤中锂成矿机理和开发利用提供参考。
The occurrence of trace elements and formation mechanism can provide important geochemical basis for the formation of coal seam. The sequential chemical extraction experiment （SCEP） is frequently used in researching the occurrence of trace elements qualitatively and quantitatively. Formerly, the SCEP is mainly applied in researching on pernicious elements, while recently,in the existence form of beneficial microelements in coal,and the researching of lithium of coal is still in infancy. The progress of the application of SCEP to study the occurrence of harmful and beneficial trace elements in coal is summarized, and the elements in coal with different occurrences are classified. Using the SCEP to reveal the occurrence of lithium in coal will provide impor tant message for the mineralization mechanism and exploitation of lithium in coal.
