摘    要:运用高分辨率电离耦合等离子体质谱(HR ICP-MS)、电离耦合等离子体原子发射光谱(ICP-AES)、冷原子吸收光谱(CV-AAS)、原子荧光光谱(AFS)、离子选择性电极法(ISE)等方法测试了开滦矿区晚古生代47个煤样中的微量元素;采用储量权衡的方法,计算了开滦矿区煤中微量元素的均值,并与地壳克拉克值、华北地台晚古生代煤中均值、全国煤中均值进行了对比.研究发现,开滦矿区晚古生代煤中As(6.61 μg/g)、Cd(0.2 μg/g)、Cr(29.91 μg/g)、Cu(34.98 μg/g)、Ni(15.44 μg/g)和Zn(67.89 μg/g)等潜在的微量有害元素偏高,值得关注;并在我国煤中检测出了Re元素.

关 键 词:开滦矿区  微量元素  储量权重  晚古生代

Abstract:The trace elements in forty seven Paleozoic coal samples from the Kailuan coalfield, Hebei Province, China, were determined using high resolution inductively coupled plasma mass spectroscopy (ICP MS), inductively coupled plasma atomic emission spectroscopy (ICP AES), cold vapor atomic absorption spectrometry (CV AAS), atomic fluorescence (AFS), and ion selective electrode (ISE) techniques.The method of reserves balance was used to calculate the concentrations of trace elements in coal.In addition, the concentrations of trace elements in this coalfield were compared with those in the earth crust, those in the Paleozoic coals from North China, and those from Chinese coals.The studies show that elements, such as As (6.61 μg/g), Cd (0.2 μg/g), Cr  (29.91 μg/g), Cu (34.98 μg/g), Ni (15.44 μg/g), and Zn (67.89 μg/g), are much higher in the coals from the Kailuan coalfield.Re was detected in Chinese coals.
Keywords:Kailuan coalfield  trace elements  reserves balance  the Paleozoic age
