mathematical model previously developed for the absorption at 20 degrees C of sulphur dioxide into sulphuric acid solutions containing hydrogen peroxide was adapted to take the effect of the temperature into account. This model was exploited to determine at 35 and 50 degrees C the overall kinetic parameter relative to the absorption-oxidation of SO2, for increasing H2SO4 molarities (from 1 to 6.4 M) and in the presence of a variable concentration of H2O2 (1.2-4.4 M) from absorption test runs performed in a cables-bundle laboratory scrubber. It was clearly observed that an increase in temperature enhances the global process of SO2 absorption (solubility + diffusion + reaction), whereas at a given temperature, an increase in the sulphuric acid content slows down the process.
