PAHs(Polynuclear Aromatic Hydrocarbons)에 오염된 토양 회복공정으로서 마이크로파의 적용성 검토연구 = Applicability on Microwave Technology to the Remediation of PAHs(Polynuclear Aromatic Hydrocarbons) Contaminated Soil

다국어 초록 (Multilingual Abstract)

The fate of polynuclear aromatic hydrocarbons(PAHs) in soil has drawn increasing concern due to their toxic, carcinogenic, and mutagenic effects. These compounds have been most commonly carried into the soil in solvent, as in a coal tar or cresote
This study has been focused on the applicability of microwave treatment of soils contaminated by PAHs studies have been conducted with soil(particle diameter 150∼500㎛), which was spiked with naphthalene, acenaphthene, fluorene, anthracene and pyrene, with different moisture contents According to the results of the research, up to 95% removal efficiency of naphthalene was observed in 10% moisturized soil for five rninutes microwave inducing. And the removal efficiency of acenaphthene and fluorene were observed to be 88.9%, 67.2% in 30% moisturized soil, respectively Due to the low wapor pressure, anthracene and pyrene showed the low removal efficiency In case the powdered activated carbon was added to the soil as a sensitizer, anthracene and pyrene were decomposed into a various by-products Decomposition rates of anthracene and pyrene were increased with incresing addition of a PAC to the soil It is concluded that the developement of a microwave process to remediate soils contaminated with PAHs is foreseeable. But additional studies are also needed regarding continuous microwave heating process.
