| Abstract |
The scientific literature pertaining to the oxidation of SO2 in power plant plumes is reviewed. Aqueous phase, homogeneous gas phase, and heterogeneous gas phase mechanisms are considered, as are actual plume studies. The reported rates vary over a wide range, which is not totally unexpected due to the highly complex nature of the oxidation process, and some general conclusions can be drawn: (1) Recent plume studies, in general, indicate lower rates than earlier ones, and also suggest a coincidence between the reappearance of ozone in the plume and oxidation of SO2. (2) Gas phase studies indicate homogeneous reaction of SO2 with OH radicals and heterogeneous reactions catalyzed by lead and iron to be perhaps the most significant processes; (3) In the aqueous phase, the reaction is most effectively catalyzed by iron and manganese, and ammonia plays an important role in promoting the oxidation by maintaining a high pH. |
