Abstract

2,6-dithiol-4-methyl­phenol(DTMP) as a photometric reagent for the extractive spectro­photometric  determination of  iron(III) is presented in this paper. The reagent DTMP in the pre­­sence of amino­phenols (AP) gave instantaneous and stable red  colour with  iron(III) in the pH range 4.2 to 5.3. The Beer’s law was applicable in the range of 0.4 – 20 μg/ml at 550-556 nm. The limit of detection (LOD)  is found to be  9.3-9.7 ng/mL. The stoichiometry of the complex is established as 1:2:2 (Fe: DTMP: AP) by equilibrium shift, relative yield, Asmus straight line and the intersection curves method.  The standard deviation and the coefficient of variance are presented. The proposed method has been successfully applied for determination of Fe(III) in  pharmaceutical, food and in plant samples are presented.
