| Abstract: | The kinetics of autoxidation of sulphur (IV) in acetate buffered aqueous suspensions of limestone powder in the condition [S(IV) ≤1 x 103 mol dm-3 obey the rate law which is first order in each of [limestone] and [S(IV)] and inverse first order in [H+]. On the other hand, in the condition [S(IV)] > 1 x 10-3 mol dm-3 a different kinetics rate law which is first order in [limestone], second order in [S (IV)] and inverse first order in [H+] is obeyed. The calculations indicate that a slurry containing 1.0 g dm-3 limestone will remove 90% of dissolved aqueous SO2 (1 x 10-3 mol dm-3) in less than a minute at ph 6 and 40o C. |
