AbstractRadiation decomposition and aerosol formation of various volatile organic compounds (VOCs) were examined to get information on a treatment of industrial off-gas. Model gases, air containing aromatic VOCs, chloroethenes and 1,2-dichloroethane, were sealed in batch reactors and irradiated with electron beam (EB) and gamma ray. For aromatic VOCs, G-values of decomposition in gamma ray irradiation were about 1.5 times larger than those in EB irradiation. The ratios of aerosol formation to decomposed aromatic VOCs were ranged from 30 to 66% on the basis of carbon. For chloroethenes except monochloroethylene, G-values of decomposition were 6 to 45 times larger than those of aromatic VOCs and the irradiated product was mainly gaseous compound. The G-values of decomposition in EB irradiation increased markedly with increase of chlorine atom in a molecule, while those in gamma ray irradiation were almost kept constant.
