| 英文摘要 | To degrade the chlorobenzenes from contaminated soil, herein, a novel peroxomonosulfate-ferrate-FeS (PFI) hybrid oxidation system has been proposed. Take the o-dichlorobenzene as a typical contaminant, results of bottle tests show that the PFI oxidation system performs well in removing the pollutant, achieving up to 93% of removal efficiency in less than 30 min. With the orthogonal experiments, the effects of different parameters on the degradation of o-dichlorobenzene have been systematically investigated. The degradation of the o-dichlorobenzene by the PFI oxidation system is found to be well matched by the quasi-first order kinetic model. Further mechanistic study shows that, in this system, a proper addition of FeS could not only facilitate the activation of persulfate to produce sulfate radicals to oxidize o-dichlorobenzene, but also enhance the conversion of ferrate(VI) to produce Fe(V) and Fe(IV) to attack o-dichlorobenzene. In this way, the peroxomonosulfate and ferrate could perform synergistically with the presence of FeS in degrading the o-dichlorobenzene. The o-dichlorobenzene is found to be degraded into o-chlorophenol, 2,3-dichlorophenol, 3,4-dichlorophenol and chlorohexane, and finally to be CO2, H2O, HCl. In addition, results also show that the application of PFI oxidation system could reduce heavy metals in the soil and improve the soil permeability. (C) 2021 Taiwan Institute of Chemical Engineers.
