Abstract
Photooxidation of cumene (isopropylbenzene) and pyridine in dilute solution in natural waters gives products characteristic of reactions with alkylperoxy (RO 2 ⋅) and hydroxyl (HO⋅) radicals. On the basis of the rates of formation of the products, the average concentrations of RO 2 ⋅ and HO⋅ are estimated to be about 10 -9 and 10 -17 mole per liter, respectively. The concentration of RO 2 ⋅ is large enough that, for some classes of reactive chemicals, oxidation can be an important process in natural waters.Keywords
