摘要：

Iron (III) iminodiacetate (FeIDA) phototransformation was studied at 20-degrees-C under monochromatic excitation in acidic medium. A wavelength effect is observed : the quantum yield of FeIDA transformation goes from 0.2 at 405 nm up to 0.53 at 254 nm. The iron (II) formation is directly related to FeIDA disappearance. No decomplexation appears to take place. The photoproducts of the reaction are glycine and glyoxylic acid. The loss of an acetate group does not lead to the formation of HCHO and CO2 as described for iron(III)nitrilotriacetate.
