| 摘 要： | 利用电感耦合等离子体质谱（ICP-MS）检测了新疆306个煤样中钴含量，结果表明新疆煤中钴含量均值高于世界煤和中国煤均值，新疆早侏罗世煤中钴含量远高于中侏罗世。统计分析揭示，准东和准南煤田煤中钴主要以无机结合态存在，库拜和伊犁木斯乡煤中钴主要以有机结合态存在，其他新疆煤中钴为有机和无机结合态共存。综合分析认为，新疆煤中钴的分布主要受控于沼泽中地下水位和源区母岩性质的影响。

| Abstract: | Cobalt in 306 coal samples from Xinjiang was determined by inductively coupled plasma mass spectrometry (ICP-MS). The Co concentrations of coal in Xinjiang are obviously higher than Co concentrations both in China and abroad, and the cobalt content of the early-Jurassic coal is much higher than that of the middle-Jurassic coal in Xinjiang. Statistics show that Co is existent predominantly in the organic binding state in coals of Kubai and Musixiang within Yili, associated mainly with inorganic matter in coals of eastern and southern Junggar, and related to organic and inorganic matters in coals of other places in Xinjiang. The concentrations of cobalt in these coals are controlled by the groundwater table in swamp and the properties of parent rocks in the source area. |
