PHENANTHROIMIDAZOLE-AZO DERIVED POLYMER BASED FLUORESCENCE SENSOR DESIGN FOR MONITORING OF Fe (III) IONS

Abstract

Dye doped polymer films which are sensitive to Fe (III) ions have been developed for using in the aqueous medium. PVC films were obtained by spreading the cocktail mixture onto a mylar film used as a supporting material. PMMA films were prepared with solvent casting method. Cation responses were examined for two different polymer films. Emission bands were obtained at different concentrations of Fe (III) ions. Because polymer films had the highest response to them. The calibration graphics were plotted for emission values at different Fe (III) concentrations. Besides, interference effects of Cr (III) and Fe (II) ions to Fe (III) ions were studied. Additionally, regeneration studies were carried out to examine application properties of the dye doped polymer films developed as a sensor for Fe (III) cations.
