The fluorophotometric determination ofgallium(Ⅲ) with eriochrome blue black R (ECBBR) was investigated in the presence of OP at pH 2.0-3.5. The calibration graph has a good linear relationship in the range of 1.6× 10 7 1.2×10 5 mol/L Ga(Ⅲ). The effect of foreign ions was studied and the proposed method was applied to the determination of gallium in aluminum alloy.
