Free-Radical Oxidants in Natural Waters

Theodore Mill; Dale G. Hendry; Harold Richardson

Photooxidation of cumene (isopropylbenzene) and pyridine in dilute solution in natural waters gives products characteristic of reactions with alkylperoxy (RO2�) and hydroxyl (HO�) radicals. On the basis of the rates of formation of the products, the average concentrations of RO2� and HO� are estimated to be about 10–9 and 10–17 mole per liter, respectively. The concentration of RO2� is large enough that, for some classes of reactive chemicals, oxidation can be an important process in natural waters.
