Abstract Vanadium is a trace metal that is found in crude oil and its derivatives, in water from oil production, and in rocks. Methods to determine the amount of vanadium in these materials is of great interest to the petroleum industry. Its presence is related to problems of corrosion in processing plants, poisoning of catalysts, undesirable side reactions in refining operations and it is in air pollution from burning fuels. In addition, the ratio of V/Ni concentration can be used to reveal the geographical origin of oil. In this review, strategies using atomic spectrometry techniques for the determination of vanadium in samples of interest to the petroleum industry are discussed. The analytical techniques already consolidated and those that have been developed in recent years, as well as methods of sample preparation are approached.

石油工业中感兴趣的样品中钒的光谱测定分析策略

摘要 钒是一种微量金属，存在于原油及其衍生物、石油生产的水中和岩石中。石油工业对测定这些材料中钒含量的方法非常感兴趣。它的存在与加工厂腐蚀、催化剂中毒、精炼操作中不良的副反应以及燃烧燃料造成的空气污染等问题有关。此外，V/Ni 浓度比值可用于揭示石油的地理来源。在这篇综述中，讨论了使用原子光谱技术测定石油工业感兴趣样品中钒的策略。已经整合的分析技术和近年来开发的分析技术，以及样品制备方法也在讨论中。
