摘要
The fluorophotometric determination of gallium(Ⅲ) With eriochrome blue black R (ECBBR) was investigated in the presence of OP at pH 2.0n.5. The calibration graph has a good linear relationship in the rabid 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.
