- Abstract
- The effect of polarity on the oxidation of Hg(0) was examined in the presence of O(2) via a pulsed corona discharge (PCD). The experimental result showed no difference in the energy yield of Hg(0) oxidation at both positive and negative PCDs (similar to 8 mu g Hg W h(-1) at following conditions: total flow rate = 2 L min(-1) (Hg(0) = 50 mu g N m(-3), O(2) = 10%, and N(2) balance), temperature = 150 degrees C, and specific energy density = 5-15 W h N m(-3)). This suggests that the positive PCD process used to control gaseous air pollutants may play an essential key role in Hg(0) oxidation because it consumes enough energy (similar to 15 W h N m(-3)) but an electrical precipitator could not because it consumes less energy (similar to 0.3 W h N m(-3)) to oxidize Hg(0).
