石油加工近来大量采用催化过程,因而对石油及催化剂中所含微量金属,如铁、镍、钒、钠等,提出了准确测定的要求。为了考察润滑油在使用过程中机械的磨损及腐蚀情况,也需要分析油中金属含量的增减。在我们比较商品油样的组成及性能时,常常需要有金属的分析结果。原油地质工作者从石油中微量金属提供的数据来探讨石油的成因,油层年代及地层对比等。这些样品的性质变化很大,分析的灵敏度及速度都要求较高,要求分析的元素种类也很多,因此选择了干扰较少,可以直接定性,样品予处理手续较简单的发射光谱 Recently, petroleum processing has been widely used in catalytic processes, and thus accurate requirements for accurate determination of trace metals such as iron, nickel, vanadium and sodium contained in petroleum and catalysts have been proposed. In order to investigate the lubricating oil in the process of mechanical wear and corrosion, but also need to analyze changes in the oil content of the metal. When we compare the composition and performance of a commercial sample, it is often necessary to have a metal analysis. Crude oil geology workers from the oil to provide the data of trace metals to explore the causes of oil, reservoir age and stratigraphic contrast. These samples vary greatly in their properties, their sensitivity and speed of analysis are high, and the number of elements required for their analysis is large, so they have less interference and can be directly qualitatively determined. The emission spectra of samples with simpler procedures
