Abstract In the present paper, the fluorescence spectral behavior of gallium with trimethoxyphenylflurone (TM-PF) in microemulsion was studied. In the buffer medium of HAc-NaAc at pH 4.95，the fluorescence intensity is in proportion to the concentration of gallium (Ⅲ) in the range of 0-0.045 μg·mL-1. The CTMAB microemulsion was efficiently used to enhance the sensibility and stability of the system, and the limits of detection were 1.2 ng·mL-1. The coexistent metal ions can be separated and gallium can be enriched by the extraction of butyl acetate, greatly improving the selectivity and sensibility of the system. The method possesses high sensitivity as well as high selectivity. It can be used to determine trace amount of gallium in ore samples successfully.
