Abstract: A new Schiff base, salicylidene-8-aminoquinoline(SAAQ), was prepared and characterized by elementary analysis, IRand UV.The optimal conditions for the fluorescent complex formation of SAAQ with gallium (Ⅱ) are established in this paper.The excitation and emission wave lengths are 418 nm and 513 nm respectively, the molar ratio of Ga( Ⅱ) to SAAQ was determined to be 1:2.The quantum yield is 0.69 at pH 3.20~4.50.The proposed method was used for the determination of gallium in alloy samples in the range of 2~280 ppb.
