  • Determination of ferrous and ferric iron in aqueous

    Determination of ferrous and ferric iron in aqueous

    A solvent extraction method was employed to determine ferrous and ferric iron in aqueous samples. Fe 3+ is selectively extracted into the organic phase (n heptane) using HDEHP (bis(2 ethylhexyl) hydrogen phosphate) and is then stripped using a strong acid.After separation, both oxidation states and the total iron content were determined directly by ICP MS analysis.
