文摘

Mechanistic models for hematin-catalysed decolourization of Orange II were validated. Ineffective hematin-catalysed H2O2 dismutation was detected and simulated. High Orange II levels caused rates depletion probable by blocking hematin activation. Hematin inactivation by superoxide explained biphasic profiles during H2O2 dismutation.
