Abstract

A fluorimetric method for the determination of Fe(Ⅲ) using N,N'-oxalylbis(2-pyridyl-3'-sulphobenzoyl hydrazone)(OPSH) as a emission reagent has been developed. Determination has been performed by measuring the fluorescence intensity of Fe(Ⅲ) complex at 367 nm in aqueous solution (pH 3) with 290 nm excitation. There was a linear relationship between Fe(Ⅲ) concentration and fluorescence intensity over the range 2000∼10 ng/ml. The method has been applied to the determination of Fe(Ⅲ) in synthetic mixtures and tap water
