initial MV concentration of 1.5 × 10 −5 M. Pseudo-first order kinetics under the experimental condition was observed throughout. The observed pseudo-first order rate constants, k Ψ were obtained from slopes of ln ( A t − A ∞ ) versus time

bubbled through at 0.2 dm 3 /min. No rise in the temperature due to the heat of the reaction was observed in any of the runs since the reactor was operated with low concentration of nitrate ions ( 100 mg/dm 3 NO 3 − ). No pressure control was required as

. Outside protonation is accelerated by increasing hydrogen ion concentration but not by general acids. Inside protonation of the deprotonated peptide nitrogen occurs simultaneously with metal–N(peptide) bond breaking [ 9 ]. This pathway is accelerated by
