Kinetic and mechanistic aspects of metal ion catalysis in cerium(IV) oxidation

This review discusses the kinetic aspects of different metal ion catalysis in Ce(IV) oxidation of different types of organic and inorganic substrates in aqueous acid media. The reactions have been categorised with the metal ions acting as the catalysts. The nature of mechanism of catalysis in Ce(IV) oxidation depends on the nature of substrate for a particular metal ion catalyst and it also largely depends on the nature of acid medium used. The utility and scope of the catalytic oxidation by Ce(TV) in analytical chemistry are discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
