| Abstract: | A highly precise and rapid method for the quantitative estimation of
iron traces by substoichiometric isotope dilution analysis has been described.
The method involves the extraction of spiked (59Fe) iron(III) with
substoichiometric amounts of acetylacetone into chloroform at pH 2.0. The proposed method is free from
interferences of various closely related foreign ions, thereby establishing the
selectivity of the proposed technique. The present method has also been applied
to different certified
alloys without any pre-separation and the trace
quantities of iron are successfully evaluated. |
