Transformation of Iron(VI) into Iron(III) in the Presence of Chelating Agents: A Frozen Solution Moessbauer Study: Moessbauer Investigation of the Reaction between Iron(VI) and Chelating Agents in Alkaline Medium

摘要

Mossbauer spectroscopy is a good tool to look at the transformations of iron containing species in various reactions using the frozen solution technique. This study presents the fate of iron(VI) as being reduced to iron(III) in the presence of complexing agents, glycine and ethylenediaminetetraacetic acid (EDTA). The intermediate oxidation states, Fe~V and Fe~(IV) of the reaction were not seen within the time scale of sample freezing (≥5 s). The characterization of ferric species formed from Fe~(VI) reactions with glycine and EDTA was carried out.
