다환방향족 탄화수소(PAHs)로 오염된 해양오염퇴적물의 유사펜톤 산화처리를 이용한 정화

Abstract

It is evaluated that a certain effects of the application of Fenton-like remediation technology enhanced with surfactants in this research. Hydrogen peroxide was used as chemical oxidation reagent for Fenton-like reaction. A combination of using various concentrations of hydrogen peroxide and surfactants was evaluated to degrade PAHs in contaminated marine sediments and was yielded 0-30% removal of PAHs in the sediment for 1 hr duration of the treatment. The largest amount of removal was found in the case of applying 5M hydrogen peroxide and 0.5% Tween 80. The higher degradation efficiencies were generally observed after longer treatment time. The more PAHs can be destructed till 24 hours. The degradation efficiencies by hydrogen peroxide + 0.05% Tween 80 solution were generally higher for HMW PAHs than for LMW PAHs.Using these findings, we are currently designing bench scale pilot system to develop a commercial system to be used in harbors around the nation. The degradation efficiencies were generally higher for HMW PAHs than for LMW PAHs.Keywords : Contaminated Marine Sediment, Fenton-like oxidation, Remediation, PAHsusing various concentrations of hydrogen peroxide and surfactants was evaluated to degrade PAHs in contaminated marine sediments and was yielded 0-30% removal of PAHs in the sediment for 1 hr duration of the treatment.
