Abstract
We investigate the removal of air pollutants containing nanoparticles with a wet-type plasma reactor that generates a gas-liquid interfacial nonthermal plasma. To evaluate the performance of this reactor, we prepare a simulated exhaust gas using polystyrene latex particles, as well as gas cylinders of synthesized air and mixed gas of nitric oxide (NO) and sulfur dioxide (SO2). We achieve a partial collection efficiency of more than 99% for nanoparticles. Moreover, we obtain removal efficiencies exceeding 99% and 81% for SO2 and NOx, respectively. We confirm that the proposed reactor is useful for the simultaneous removal of nanoparticles, NOx, and SOx.
