Communication to the Editor: Photochemical Reduction of Ferric Ion by Oxalic Acid.

The Chemistry of the Metal Oxalato Complexes.

“…The first significant work on the photochemistry of Fe(C204)«8-solutions was that of Allmand and co-workers (13, 14), which has been fully confirmed in later studies (40,232,262). It is established that the overall reaction in monochromatic light at room temperature yields, in the absence of oxygen, FeC204 + 2C02, with a quantum efficiency of about 0.5.…”
