A simple and rapid method for the determination of trace amount of iron(III) by stopped-flow photochemical method has been developed based on the catalysis of iron(III) on the photochemical decoloration of methylene blue. The linear range of this method was in the range of 0.003-0.28µg/mL of iron(III). It is satisfactory to apply this method in the analysis of iron(III) in tap water and honey samples with RSD 1.80% and 1.03%, respectively.
