Abstract

Rate constants for one-electron reduction of SO, by several radicals and for reduction of several compounds by SO2'-radicals were determined by pulse radiolysis at pH 1. SO2 is reduced by the (CH3) 2COH radicals with k= 2.1 X lo9 MI a nd by viologen radicals and certain porphyrin. n-radical anions with k-108-109 M-'s-'. The SO2'-radical reduces compounds which have reduction potentials more positive than-0.28 V. The rate constants ...
