The pH dependence of the ozone absorption kinetics in aqueous phenol solutions

Using a wetted wall laboratory absorber, the rate of ozone absorption in aqueous phenol solutions has been measured in the pH range 1.75–12.The phenol concentration was varied in a wide range (7–800 ppM) and the ozone partial pressure over a six-fold range. The temperature and the liquidThe results were interpreted by assuming that the rate determining step of a reaction sequence is different in acid and basic solutions.
