【 摘 要 】

The basic principles of UV irradiation as sample pre-treatment step and its potential for inorganic analysis are illustrated and discussed through significant examples from the literature. Not only does this overview cover the classical applications of this technique in the decomposition of organic matter in electroanalysis, but it also presents recent trends, including the increasing interest in employing UV irradiation in flow analytical systems, successful attempts to enhance its effectiveness and the coupling with chromatographic and spectroscopic methodologies. Furthermore, a number of relevant cases of UV-driven derivatization reactions involving photo-sensitive inorganic species are presented, showing some convenient options to perform fast and reliable determination of inorganic and organic analytes.
