Abstract

Damped pH oscillations have been measured in the unbuffered reaction mixture of H2O2-SO32--H +-Fe-(CN)64- in a semibatch reactor when all the reagents were simultaneously flowed, at a constant controlled rate, into the reactor containing pure water in the beginning. Oscillations occurred within a limited range of the ratio of incoming reagent concentrations: 1.1 < [H2O2]0/[SO32-] 0 < 1.4; [ Fe(CN)64-]0/[H+]0 > 1.0; [SO32-]0/ [H+]0 > 2. The known simple model, consisting of the empirical rate laws of the component reactions, has successfully been used to simulate the dynamical behavior.
