A simple and sensitive spectrofluorimetric procedure for the analysis of microquantities of gallium in alloy was described. The method is based on the formation of Ga(Ⅲ)-CCA (calon-carboxylic acid) complex. The emission of the fluorescent complex was measured at λ = 620 nm with excitation atλ =584 nm. A good linearity was found in the gallium range of 0.7-280 ng/mL. The precision of the method is good and the relative standard deviation is 1.9% for a gallium standard solution of 70 ng/mL. The procedure was proved to be suitable in terms of accuracy and selectivity for the mi-croamount of gallium in alloy.
