Abstract

A column solid phase extraction (SPE) and preconcentration method was developed for the determination of Fe(III) ion in aqueous samples by flame atomic absorption spectrometry. The method is based on sorption of Fe(III) ions on natural Analcime Zeolit column modified with a new Schiff base, 5-((4-nitrophenylazo)-N-(2′,4′-dimethoxyphenyl))salicylaldimine (L), and then eluted with 0.1 M EDTA and determined by FAAS. Various parameters, such as the effect of sample pH, flow rate, volume of the sample and interference of the metal ions on the method, to optimize the conditions for determination of Fe(III) ions in aqueous samples, were studied. The recoveries were >99%. The developed method was applied to the determination of trace Fe(III) ions in drinking water and river water samples with satisfactory results.
