  This reaction is of great interest in the study of wet flue gas desulfurization processes. In the case of the normally used absorption additive lime the oxidation of S(IV) is an essential step in quantitatively producing the final product gypsum (CaSO 42H 2 O). Beside detoxication of S(IV) the dewatering properties of gypsum are improved when a high oxidation yield is achieved.
