Determination of Fe2+ and Fe3+ in aqueous solutions containing food chelators by differential pulse anodic stripping voltammetry
Journal article, 2010

The objective was to investigate interactions between iron and food chelators in an aqueous environment. The net complexation were investigated by DPASV in a NaClO4 electrolyte using a platinum electrode. The experimental conditions were simulating the environment of the human duodenum. The results indicated a net coordination affinity between Fe2+ and the organic acids in the following order; ascorbic acidphytate>pyruvate>lactate>acetate. For Fe3+ net complexation, the stability was in the order of lactate>phytate>pyruvate>acetate>citrate. In conclusion, DPASV in conjunction with a platinum electrode is suitable for studies in aqueous systems where the net complexation of metal is important.
