The photo-Fenton oxidation, which can treat high concentration and toxic organic wastewater effectively, was a kind of effective technique. This paper described the mechanism and effects of photo-Fenton oxidation. The plenty of ·OH(hydroxyl radicals) was produced in photo-Fenton oxidation. The·OH was reactive and nonselective. Its oxidizing potential was 2.8V, having strong oxidation ability, and most of organics were redox. Moreover, the further studies were presented. The virtues were easy manipulation and not contamination. The Fe3+ might react with OH, and Fe(OH)3 product was harmless to environment. The defect was that reaction was carried under pH≤3. The big wastage of H2O2 resulted in processing high-cost and so on.
