摘要：The mass transfer-reaction kinetics of NO absorption by dual oxidants (H2O2/S2O82-) was studied in a bubble column reactor. The comparison experiments in different systems showed that the combination of Na2S2O8 and H2O2 had significant synergistic effects on the rate of NO absorption. The effects of Na2S2O8 concentration, H2O2 concentration, NO concentration, pH, O-2 concentration, and gas flow rate on the rate of NO absorption were investigated. The rate of NO absorption increased with the increase in Na2S2O8 concentration, H2O2 concentration, and gas flow rate. The rate of NO absorption increased slightly with the increase in 02 concentration, whereas it increased linearly with the increase in NO concentration. At pH 11, the rate of NO absorption reached 1.31 X 10(-6) mol/m(2).s. The NO absorption by dual oxidants (H2O2/S2O82-) was pseudo-first-order with respect to the NO concentration. Moreover, a simple rate equation of NO absorption by H2O2/S2O82- was obtained. The results of the rate equation indicate that the calculated values are consistent with the experimental values.
