✦ Synopsis


The change in peak current resulting from the reaction of Fe(I1) with nitroso-R salt in a flow-injection system is used to quantify Fe(I1) with either single-or dual-electrode amperometric detectors. The current change varies linearly with Fe(I1) concentration from 0 to 200 mg 1-l. The relative standard deviation was about 5% with the single-electrode detector and about 10% with the dual-electrode detector. The method is evaluated for the determination of iron in dietary supplements.
