title: [The relative importance of different oxidants in the degradation process of quinoline using O3/UV].
abstract: In this paper the relative importance of different oxidants in the degradation process of quinoline using O3/UV was studied. O3 and .OH played the most important roles in removing quinoline. Their concentrations were measured using indigo method and .OH-probe compound (p-CBA) method respectively, and the relative importance of these two oxidants was quantitatively determined. The second-order reaction rate constant between quinoline and hydroxyl radical was calculated as 6.65 x 10(9) mol.(L.s)-1. In the present experimental condition, .OH and O3 oxidations contributing to the total degradation rate of quinoline were 88% and 12% respectively. Increasing the hydroxyl radical concentration will help to improve the total removal rate of quinoline.
