摘要：

The rate constant for the reaction between the sulphate radical (SO4.-) and the ruthenium(II) tris-bipyridyl dication (Ru(bipy)3(2+)) is (3.3+/-0.2) X 10(9) mol-1 dm3 s-1 in 1 mol dm-3 H2SO4 and (4.9+/-0.5) X 10(9) mol-1 dm3 s-1 in 0.1 mol dm-3, pH 4.7 acetate buffer. The SO4.- radical produced by the electron transfer quenching of Ru(bipy)3(2+*) by S2O8(2-) reacts rapidly with both acetate buffer and chloride ions. These side reactions result in a reduction in the overall quantum yield of Ru(bipy)3(3+) production and reduced reaction selectivity when Ru(bipy)3(2+*) is quenched by persulphate.
