Abstract
Reaction mechanisms and kinetics of manganese-catalyzed ozonation of p yruvic acid in aqueous solution are investigated. Experiments performe d in the pH range 2.0-4.0 show that the reactivity is strongly enhance d by heterogeneous and homogeneous catalytic mechanisms, which are act ivated by suspended MnO2 particles and by dissolved Mn ions, respectiv ely. Homogeneous mechanisms and related kinetics are elucidated. (C) 1 998 Elsevier Science Ltd. All rights reserved.
