Advanced oxidation processes are defined as those which involve the generation of hydroxyl radicals in sufficient quantity to affect water purification. The theoretical and practical yield of OH from O//3 at high pH, O//3/H//2O//2, O//3/UV and H//2O2/UV systems is reviewed. New data is presented which illustrates the importance of direct photolysis in the O//3/UV process, the effect of the H//2O//2:O//3 ratio in the O//3/H//2O//2 process, and the impact of the low extinction coefficient of H//2O//2 in the H//2O//2/UV process.
