本法是利用无火焰原子吸收法对高温元素进行定量分析的又一次试验,我们曾用这种手段建立了十五个稀土元素的分析。并对测定高温元素中的主要问题提出了一些解决的方法钪的测定也存在这些共性问题,报告中述及了这一方面。根据抗与铁、铝的地球化学行为,它们之间有一定的比值关系,所以方法着重考虑了铁矿石中钪分析,从其共存元素对钪的影响程度看,也适用于其他试样,样品不需经过繁琐的分离,铁矿石及稀土样品中的钪却可直接测定。稀土的存在有一定的影响,在控制一定的含量范围内可消除影响。此法操作简单、灵敏度高。
This is yet another test for the quantitative analysis of high temperature elements using flameless atomic absorption spectrometry. We have used this method to establish the analysis of fifteen rare earth elements. And some solutions to the main problems in the determination of high temperature elements are proposed. The common problems in the determination of scandium also exist. The report mentioned this aspect. According to the anti-iron and aluminum geochemical behavior, there is a certain ratio between them, so the method to consider the iron ore scandium analysis, from the extent of its co-existence of elements on scandium, but also for other samples, Samples without going through the tedious separation, scandium iron ore and rare earth samples can be directly measured. The presence of rare earth has a certain impact, in the control of a certain range of content can eliminate the impact. This method is simple, high sensitivity.
