Abstract
The absorption and oxidation of NOx gases by potassium persulfate has been
implemented to remove the NOx gases from the air by forced ventilation through wet
silica gel beads soaked with K2S2O8
/K2CO3 and (NH4)2S2O8
/K2CO3
.The influence
conditions: air flow, duration, cartridge packing, concentration of solution on the
efficiency of NOx capturing was studied. The ability to absorb NOx gases and convert into
nitrate ions was confirmed, however low efficiency ≅0.1% indicates that improvements of
the method are required. The increase of duration decreases the efficiency, and increase
of the packing increases the efficiency of absorption, however the exact magnitudes
appear inconsistent.
