摘　　要：镓的分析测定对于航天、电子、通讯、能源等行业的发展都具有重大意义。近年来各种新试剂、新方法的不断涌现 ,使镓的光度分析有了新的进展。通过对 90年代以来镓的光度分析进展予以综述 ,介绍了三苯甲烷染料、三羟基荧光酮、罗丹明B、偶氮、8 羟基喹啉 5 磺酸衍生物、希夫碱、桑色素、腙等几大类试剂在镓的分光光度和荧光光度分析中的应用 ,并对样品的分离富集方法作了评述。共引用国内文献 5 2篇。The determination of gallium is very important in the area of spaceflight, electronics, communication, energy industry and so on. Recently various new reagents and detection methods have been used to the photometric detection of gallium. In this paper, the development of photometric determination of gallium in the last 10 years is reviewed. The applications of complexing agent in the photometric determination of gallium are presented, such as triphenylmethane dyes, derivatives of trihydroxyfluorone, azo dyes, derivatives of 8 hydroxyquinoline 5 sulfonic acid, schiff base, morin as well as hydrazone. Various separation approaches and preconcentration techniques are also discussed. 52 references are cited.
