ICP-MS测定区域地球化探样品中稀土元素的研究
|
摘要
[目的]为了提高化探样品的分析质量和分析速度。[方法]通过1/5万区域地质矿产调查项目,在青海东部地区发现土壤中含有稀土元素。稀土就是化学元素周期表中镧系元素—镧(La)、铈(Ce)、镨(Pr)、钕(Nd)、钷(Pm)、钐(Sm)、铕(Eu)、钆(Gd)、铽(Tb)、镝(Dy)、钬(Ho)、铒(Er)、铥(Tm)、镱(Yb)、镥(Lu),以及与镧系的15个元素密切相关的2个元素—钪(Sc)和钇(Y),共17种元素。采用电感耦合等离子体质谱仪(ICP-MS),测试化探样品中的稀土元素。[结果]按照该研究分析方法测定稀土15种元素的结果令人满意。[结论]该方法具有操作简便、准确性良好的特点,适用于区域地球化探样品的分析测试。
[Objective] The research aimed to improve the analysis quality and analysis speed of exploration samples. [Method] Through 1 /50 000 regional geology and mineral resources survey project,the soil in the eastern region of Qinghai contained rare earth elements. Rare earth was chemical lanthanide element in the periodic table-lanthanum( La),cerium( Ce),praseodymium( Pr),neodymium( Nd),promethium( Pm),samarium( Sm),europium( Eu),gadolinium( Gd),terbium( Tb),dysprosium( Dy),holmium( Ho),erbium( Er),thulium( Tm),ytterbium( Yb),lutetium( Lu),and two elements-scandium( Sc) and yttrium( Y) which was closely related to 15 lanthanide elements,a total of 17 elements. Using inductively coupled plasma mass spectrometry( ICP-MS),rare earth elements in geochemical samples were tested. [Result] The results of 15 elements in the rare earth using the research analysis method were satisfactory. [Conclusion] The method had the characteristics of easy operating and good accuracy,which could be applied in the analysis of regional geochemical exploration samples.
