"Indirect Determination Of Iron In A Flow Injection System With Amperometric Detection"
Anal. Chim. Acta 1987 Volume 192, Issue 2 Pages 349-353
Liliana Silva R, Luis E. León and Alfredo Calvo C.

Abstract: Known volume of sample were added to 0.15 M hydroxylammonium chloride (0.5 ml) and diluted to 25 mL with 1 M acetate buffer (pH 4.7). Aliquots (20 µL) were introduced into a flow of 2.1 mM nitroso-R salt in acetate buffer (3.5 mL min-1). A 6 µL electrochemical cell used for detection incorporated a SCE and working and auxiliary electrodes made of carbon paste. The working electrodes were of 2.2 and 4.5 mm diameter and operated with applied potentials of -0.45 and +0.25 V, respectively. Rectilinear calibrations were achieved up to 200 µg mL-1 of Fe(II) for both single- and dual-electrode detection.
