Abstract
Benzene and tertiary butanol have been used as radical scavengers to d emonstrate the occurrence of sulphate radicals in the iron ion-catalys ed autoxidation of bisulphite in aqueous solution. Ferric ions are rap idly reduced to ferrus ions by HSO3- and a steady state is established between both iron species for some time. A detailed reaction mechanis m is presented. Computer simulations show that it can account for the essential features of the reaction.
