A novel kinetic procedure for the determination of trace iron(III) was proposed based on the aerial oxidation of Gallocyanine by oxygen dissolved in water at pH 7.0. The calibration graph is linear for 0.05-0.6 μm/ml, and the detection limit is 0.01 μm/ml (Fe). The present procedure is selective for iron(III) and very easy to control compared with kinetic procedures for iron. It had been used to the determination of trace iron in environmental samples, and the results were satisfactory.
