Photochemical Production of Fe(II) in Rainwater

Environmental Science & Technology, 2003
Significant concentrations of Fe(II) were produced upon irradiation of authentic rainwater with simulated sunlight. The magnitude of photoproduction was dependent on initial Fe(II), Fe(III), and hydrogen ion concentrations, with more Fe(II) photoproduction when initial Fe(III) and H+ concentrations were high and initial Fe(II) concentrations were low ...

Oxidation of flavonols with Cu(II), Fe(II) and Fe(III) in aqueous media

Journal of the Chemical Society, Perkin Transactions 2, 2000
Reactions of flavonols, 3-methoxyflavones, and flavones with Cu2+, Fe3+, and Fe2+ in acidic aqueous solutions with three different organic modifiers are investigated. Complexation may be followed by an oxidation of flavonols, yielding additional peaks in HPLC chromatograms of the reaction mixtures.

Mobile carrier ionophores for Fe(II)

Biochimica et Biophysica Acta (BBA) - Biomembranes, 1977
A23187 and certain other carboxylate ionophores are capable of transferring Fe(II) but not Fe(III) across phospholipid bilayers (liposomes) and red cell membranes. A23187 is able to transfer Fe(II) from ferritin loaded liposomes when allied with a suitable redox couple and sink.
