Abstract

5-(p-hydroxybenzylidene)-Thiazolidinedione-2,4 (L) as a photometric reagent for the extractive spectrophotometric
determination of iron(III) is presented in this paper. The reagent L gave instantaneous and
stable red colour with iron (III) in the pH range 3.8 to 5.2. The Beer’s law was applicable in the range of
0.05 - 3.2μg/ml at 535 nm. The Limit of Detection (LOD) is found to be 12 ng/mL. The stoichiometry of
the complex is established as 1:2 (Fe: L) by equilibrium shift method. The standard deviation and the
coefficient of variance are presented. The results of the prescribed procedure applied for the determination of
the micro amounts of Fe (III) in pharmaceutical, food and in plant samples are presented.
