The oxidation of organic compounds by Fenton processes using Fe 2+ as a catalyst generally proceeds via two stages: a fast one and a much slower one. The fast stage is attributed to a reaction between Fe 2+ and H 2 O 2, while the slower one is due to the accumulation of Fe 3+ and a low recovery of Fe 2+ by H 2 O 2 [ 18, 37 ].
