Abstract
Reduction of carbonyl-conjugated radicals by TiIII and FeII in aqueous solution has been investigated by e.s.r. spectroscopy and pulse radiolysis. Kinetic data have enabled the importance of such reactions in metal ion–hydrogen peroxide systems to be assessed. For example, reduction by TiIII at pH 1 is negligible under typical flow system conditions whereas at pH 7 reduction by TiIII–EDTA can provide an important pathway for radical termination. The dependence of reduction rates on radical structure has been investigated.Keywords
