| 摘 要： | 采用电感耦合等离子体发射质谱仪(ICP MS)测定了吉林省油页岩中铂族元素的含量,并对油页岩中铂族元素的化学特征、与无机组分的相关性及其分布模式等进行了分析和阐述。通过油页岩中铂族元素的含量与地壳和中国东部出露地壳中铂族元素丰度的比较表明,Rh、RuI、r等元素相对富集,其中松原油页岩中RhI、r的含量约为地壳平均值的10倍。研究区油页岩中铂族元素以Pt Pd分配模式为典型特征,一般Pt的丰度大于Pd。油页岩中铂族元素与无机组成相关分析的结果表明,油页岩中铂族元素可能呈吸附态存在于高岭石、伊利石等粘土矿物中。

| Abstract: | The contents of platinum group elements(PGEs) in the oil shale from Jilin Province were determined by the inductively-coupled plasma mass spectrometry(ICP-MS).The chemical characteristics,correlation of PGE to the inorganic components and the distribution model of the PGE in the oil shale samples were described and reviewed in this paper.By comparing the average contents of PGE in oil shale with the abundance of PGE in the earth's crust and in the exposed crust in East China,clearly Rh,Ru,Ir are enriched in the oil shale samples,and the abundance of Rh,Ir is about 10 times richer than that of the earth crust.The distribution of PGEs in the oil shale is characterized by Pt-Pd pattern,and generally Pt is richer than Pd.The positive relationship between PGEs and inorganic components shows that the PGEs probably occur in clay minerals such as kaolinite,glimmerton in adsorbed state. |
