Abstract
The paper describes a simple, sensitive, and selective spectroscopy method for the determination of Fe by curcumin reagent and iron(III). In acid media, a 1:2 complex was formed; its properties were identified by UV-VIS, FTIR, Raman, and MS spectra. The maximum absorbance of UV-Vis spectra appeared at 518 nm. The parameters of the method for the determination of Fe was validated. Beer’s law was obeyed in the range 0.2×10 M to 2.0×10mol/L of Fe. The limited of detection (LOD) and limited of quantitation (LOQ) has been to be 0.5.0×10 6 and 1.5×10 mol/L. This method was applied to determine the concentration of ferrous total in various samples.
