we have been researching air cleaning technology using gas-to-particle conversion of atmospheric gaseous pollutants by UV light irradiation. We measured removal efficiency of NOx and typical airborne cycloalkene, cyclohexene, by the irradiation of high power UV (with 184.9 nm wavelength) lamps. The removal efficiency of NOx increased with increasing water vapor concentration. More than 90 % removal efficiency could be achieved when the relative humidity was more than 50 %. Cyclohexene was almost removed even under low relative humidity (25 % RH). Larger particles were formed in NO- cyclohexene-air system than in NO-air system. The decrease in the removal efficiency of NOx by the addition of cyclohexene could be ascribed to the competitive reaction of OH radicals with NOx and cyclohexene. Absorption bands of carboxyl groups were visible in FT-IR spectra of collected particles which were formed in NO-cyclohexene-air-photoirradiation experiments. This technique can be applied to larger-scale air treatments if more UV lamps are added.
