摘要

摘要: 紫外光化学蒸气发生（UV-PVG）是一种绿色的样品引入技术，作为接口已被成功应用于结合光谱与质谱检测领域，实现对目标元素的检测. 方法简单高效，试剂用量少，可用于现场式检测. 同时，UV-PVG也拓宽了化学蒸汽发生元素范围，不仅可应用于As、Hg、Sb、Pb等可氢化物发生元素，还可以应用于过渡金属元素包括Cd、Fe、Co、Ni、Os以及非金属元素中的I、Br. 从机理推测、应用范围、优缺点和发展趋势方面对UV-PVG进行了阐述.

Abstract: Ultraviolet photochemical vapor generation (UV-PVG) is a newly green sample introduction technology. It has been successfully used as an interface to combine spectroscopy and mass spectrometry to detect target elements. The method is simple and efficient, with low reagent usage, and can be used for on-site detection. And the UV-PVG also broadens the range of elements of chemical vapor generation, which can be applied not only to hydride generating elements such as As、Hg、Sb、Pb, etc., but also to transition metal elements including Cd, Fe, Co, Ni, Os, and non-metallic elements such as I, Br. The mechanism application scope, advantages and disadvantages, and development trend of UV-PVG were discussed.
