Autoxidation of S(IV), in buffered solutions,conforms the rate law (1). The increase in buffer concentration has a<BR><I>R</I><SUB>obsd</SUB>=<I>k</I><SUB>5</SUB>[CdO][S(IV)]<SUP>2</SUP>[H<SUP>+</SUP>]<SUP>−1.22</SUP> (1)<BR>rate decreasing effect. On the other hand, in unbuffered solutions the kinetics obey a different rate law (2).<BR><I>R</I><SUB>obsd</SUB>=(<I>k</I><SUB>10</SUB>+<I>k</I><SUB>11</SUB>[CdO])[S(IV)][H<SUP>+</SUP>]<SUP>−0.5</SUP> (2)<BR>In both situations, the dissolution of CdO accompanies the autoxidation. A heterogeneous catalytic mechanism involving adsorption of both dioxygen and sulfur(IV) on the surface of CdO particle has been proposed.
