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.
