改进了传统的四酸溶解化探样品的方法,在传统的基础之上加入高沸点酸,加盖、复溶,克服以往敞开式溶矿的不足,结合地球化学样品的特点,充分溶解样品中铌和钽。在测定方式上,采用美国新型等离子质谱XSERIES-2,并灵活使用软件中的切换功能,进一步克服了谱线干扰和仪器漂移。此方法易于操作,适合于大规模实验生产。本方法用国家标准物质进行验证,测定结果和标准值吻合。
The traditional method of dissolving the geochemical sample is improved. The traditional method is to add high boiling point acid, capping and reconstitution to overcome the shortcomings of the previous open-type ore-dissolving and to fully dissolve the sample according to the characteristics of geochemical samples Niobium and Tantalum. In the determination of the way, the use of new plasma spectroscopy XSERIES-2 in the United States, and the flexibility to use the switching function in the software to further overcome the spectral line interference and instrument drift. This method is easy to operate, suitable for large-scale experimental production. This method is validated with national standards, the measured results and the standard values ?? match.
