ABSTRACT

In syringe-supramolecular dispersive liquid-liquid microextraction followed by flame atomic absorption spectrometry has been designed for extraction and speciation of iron in different samples. Fe(III) is complexed with 4,5-dihydroxy-1,3-benzendisulfonic acid (Tiron), neutralised through the formation of the ion pair with the ionic liquid of 1-hexadecyl-3- methylimidazolium bromide, and extracted into the reverse micelles of decanoic acid (DA) in tetrahydrofuran (THF). Total iron was determined after oxidation of Fe(II) to Fe(III). Fe(II) concentration was determined from the difference between the total iron and Fe(III) concentrations. Under optimal conditions, the calibration graph was linear up to 45.0 µg L−1 of Fe(III). The limits of detection (LOD) and quantification (LOQ) were 1.04 µg L−1 and 3.45 µg L−1, respectively. The method was applied to the analysis of iron species in various water samples as well as total iron in food samples.
