title: Spectrophotometric determination of iron in sea-water by solvent extraction as the ternary complex iron(II)-2-nitroso-4-chlorophenol-rhodamine B.
abstract: Iron has been determined in sea-water by extraction of the ternary complex of iron(II) with 2-nitroso-4-chlorophenol and Rhodamine B at pH 4.7 and measurement at 558 nm. Toluene is used as the organic solvent. Any iron(III) is reduced with hydroxylammonium chloride.
