| Abstract: | A highly sensitive method is described for the determination of iron (III). Iron(III) forms a brown coloured complex with 3-hydroxy-2-(2-thienyl)-4H-chromen-4-one (HTC) in acidic medium which is conveniently extracted into chloroform. The absorbance of the complex is measured at 415 nm. Beer's Law is obeyed up to 1.4 μg/ml with the molar absorptivity of 5.27×104 l/mol/cm. The method is quite simple, sensitive and selective and has been employed for analyzing some synthetic samples, chemicals and brazing solder. |
