氢化物-原子吸收和原子荧光法对于测定砷、锑、铋、锡、硒、碲、锗等元素具有很高的灵敏度,由于这些元素在冶金、环保、生物、医药及地球化学找矿等各领域中的重要性,近年来氢化物-原子吸收法得到了广泛的应用。但是此法存在的干扰较多,早期的工作只提出哪些元素产生干扰及干扰的程度。此后文献上陆续报导了一些消除干扰的方法,如Belcher等建议用EDTA消除铜、钴、镍对砷及锑的干扰。Kirkbright采用加入碲的方法来减弱铜对硒的干扰。Welz加入铜克服硒对砷的干扰。但是,由 Hydride - atomic absorption and atomic fluorescence spectrometry for the determination of arsenic, antimony, bismuth, tin, selenium, tellurium, germanium and other elements with high sensitivity, due to these elements in metallurgy, environmental protection, biology, medicine and geochemical prospecting, etc. The importance of the field, in recent years hydride - atomic absorption method has been widely used. However, there is more interference with this method. Earlier work only proposed which elements produced interference and interference. Since then, some methods of eliminating interference have been reported in the literature. For example, Belcher et al. Proposed using EDTA to eliminate the interference of copper, cobalt and nickel on arsenic and antimony. Kirkbright uses tellurium to reduce copper interference with selenium. Welz adds copper to overcome the interference of selenium to arsenic. However, by
