贵州燃煤型地方性砷中毒地区煤的矿物组成

Mineral composition of coals from coal combustion endemic arsenosis areas in Guizhou Province

摘要: 采用低温灰化（LTA）和X衍射粉晶分析（XRD）,结合带X光能谱的扫描电子显微镜（SEM—EDX）等方法研究了贵州燃煤型地方性砷中毒地区煤的矿物组成,计算了各矿物的相对含量,初步探讨了煤中主要的含砷矿物。

Abstract: The mineral composition of coals from coal combustion endemic arsenosis area in Guizhou Province is studied with low temperature ashing, X-ray diffraction, scanning electron with energy-dispersive x-ray analyzer, the fraction of minerals is calculated and As-bearing minerals are discussed.
