제목 Chemical degradation of the PCBs-contaminatied soilds
초록 The chemical degradation of PCBs in soil was carried out in the presence of methanol, 4,4’-Dipyridyl, Fe3+ and H2O2. The PCB mixtures could successfully be transformed into CO2and Cl-, andthe degradation reaction was suggested to occur with hydroxyl radical(OH). The hydroxyl radical was believed to be formed from the reaction of H2O2 with Fe2+ which had been reduced from Fe3+ by the charge transfer between methanol and 4,4’-Dipyridyl. The hydroxyl radical-induced PCBs degradation was composed of two sequential steps, that is, the dechlorination and the oxidation of the dechlorinated intermediates into carbon dioxide. The produced dechlorinated intermediates were proposed to be oxidized completely and very quickly.
