摘要
以山西平朔矿9#煤为研究对象,利用电感耦合等离子质谱测定煤中镉、铬和铊有害微量元素的含量。利用suffer软件生成镉、铬和铊元素在矿区中的平面分布图。结果表明平朔矿区9#煤中的镉、铬和铊含量的平均值分别为0.15μg/g、17.39μg/g和0.12μg/g,其中镉和铊低于华北煤、全国煤和美国煤均值;铬高于华北煤、全国煤和美国煤的均值。EF1分别为0.75、0.17和0.28,EF2分别为2.8、0.65和0.01。镉、铬和铊赋存在黄铁矿和粘土矿物中。
The contents of harmful trace elements including Cd, Cr and T1 of coal in the 9#coal of Pingshuo mining area, are determined by ICP - MS. The planar distribution map of Cd, Cr and T1 elements of the mining area is generated by suffer software. The results show that the average content of Cd, Cr and T1 elements in the 9#coal of Pingshuo mining area are 0. 15μg/g,17.39μg/g and 0. 12p, g/g. The average content of Cd and T1 elements in the 9#coal of Pingshuo mining area is lower than North ChinaS, the whole China＇s and Ameriea＇s, while the average content of Cr elements in the 9#coal of Pingshuo mining area is higher than North Chinag, the whole China＇s and America＇s . Their concentration factor, EF1 are 0.75,0.17 and 0.28, and EF2 are 2.8,0.65and 0.01. Cd and T1 are mainly in iron pyrite, while Cr is mainly in iron pyrite and clay pits.
