| Abstract |
Kinetics studies of the indirect photooxidation of trace hydroxyl radical (OH) probes in aqueous solutions were used to evaluate the nature and formation efficiency of the transient oxidants that are generated when hydrogen peroxide reacts with Fe(II) that is produced from photoreduction of Fe(III) at wavelength 436 nm. Results of studies of these 'photo-Fenton reactions' under various test conditions are in good agreement with the hypothesis that Fe(sup 2+) and its oxalate, citrate, and phosphate complexes react with H2O2 efficiently to produce OH in water at pH values ranging from 3 to 8. Such reactions involving Fe(II) and H2O2 provide a generally important pathway for oxidations in the environment and possibly for the treatment of contaminated waters.
