Abstract: The otherwise slow reaction between TI(III) and H2O2 goes to completion in a few seconds in the presence of 10-6 mol dm-3 Fe(II). The reaction involves a cycle of steps with reactive intermediates such as Tl(II) and HO2 [Fe(III)] >.1 x 10-4 mol dm-3 is very effective and [Fe(III)] < 1 x 10-5 mol dm-3 has no effect at all on the reaction. Cerium(IV) and Mn(III) induce TI(III) - H2O2 reaction and the extent of reduction of TI(III) depends on the absolute and relative concentrations of the reactants. Ag(II) and Cr(III) are without any effect, but vanadium(IV) induces the reaction.
