前言金属β-二酮螯合物为无机气相色谱发展开辟了途径。七十年代主要研究氟取代的乙酰丙酮金属螯合物在填充柱上的色谱性质,报导较多、应用甚广的是铍、铝和铬的测定。近年来人们对毛细管色谱的研究,特别是惰性、高效、稳定性能良好的毛细管柱的研制成功,使无机色谱向着多元素、多组分、同时测定的方面发展。在氟取代和烷基取代的二硫代氨基甲酸金属螯合物的毛细管色谱方面取得了新的研究结果,Hartmetz用毛细管柱将二(三氟乙基)二硫代氨基甲酸用于测定海水中ppb级的锌、铜、镍。毛细管色谱的研究
Introduction Metal β-diketonate chelates have opened the way for the development of inorganic gas chromatography. In seventies, mainly on the fluorine-substituted acetylacetone metal chelate chromatographic properties on the packed column, reported more widely used is the determination of beryllium, aluminum and chromium. In recent years, the research on capillary chromatography, especially the successful development of inert, efficient and stable capillary columns, has led to the development of inorganic chromatography toward multi-element, multi-component and simultaneous determination. New results have been obtained in the capillary chromatography of fluoro-substituted and alkyl-substituted dithiocarbamate metal chelates, which are used by Hartmetz for the determination of seawater with a capillary column ppb level of zinc, copper, nickel.
