Abstract

The experiment was designed for Fe3+ aqueous oxidation SO 2 in buffered or non- buffered acid solution and given the discussion on the several possible mechanisms of this reaction. With the measurement of the SO2 absorption in the different reaction systems designed, the reaction was identified as the semi-conductor or transient metal mechanism, and the kinetic rate was controlled by the progress of Fe3+ aging. Such result provided the theoretical basis for the use of dilute Fe3+ solution in the flue gas desulfurization and the explanation of fog water acidification.
