摘要
从三个方面对煤及其燃烧产物中无机组分的分析方法进行了比较和评价 :1 )比较和评价了煤及其燃烧产物中矿物分析方法 ,其中主要讨论了 XRD法和 CCSEM法 ;2 )比较和评价了煤及其燃烧产物中元素含量的分析方法 ,主要包括 X-射线和 v-射线技术 ;原子吸收或发射技术( AAS/ AES)和质谱法 ( MS) ;3)比较和评价了煤及其燃烧产物中微量元素的赋存形态分析方法 ,主要包括直接分析方法和间接分析方法 .
In this paper, analytical methods for inorganics in coal are reviewed on three fronts which are methods for determining the mineralogy of coals,methods for determining elemental concentrations,and methods for determining modes of occurrence (speciation) of trace elements in coal. Accurate determinations of both association and coal mineralogy would lead to significant and much-needed refinements of models for the behavior of inorganics in both coal cleaning processes and coal combustion.Sample preparation and incremental enhancements will continue to be made in analytical methods for elemental concentrations.Regarding to the modes of occurrence of trace element ,there are mainly indirect and direct methods .
