Recent Progress of Photometric Determination of Gallium

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.
