(A) First 300 μs of the reaction of SOR (100 μM) with O₂^·̅ (3 μM), generated by pulse radiolysis, followed at 580 nm, in the presence of 0, 1, and 1.2–10 molar equivalents of ferrocyanide, with respect to SOR, at pH 7.6. The lines were calculated for best fit to an exponential model. (B) Dependence of the observed rate constants k_1app on ferrocyanide concentration. (B Inset) Shown is the dependence of k_1app versus SOR concentration in the presence of 5 molar equivalents of ferrocyanide with respect to SOR.
