Chemical Oxidants for Remediation of Soils Contaminated with Polycyclic Aromatic Hydrocarbons at a Coking Site
不同化学氧化剂对焦化污染场地多环芳烃的修复效果

Different oxidants were evaluated for removal of polycyclic aromatic hydrocarbons(PAHs) from contaminated soils at industrial coking sites with the use of simulating device,and the fate of pollutants during the treatment was investigated.Permanganate showed the highest PAHs removal rate(96.2%) of the oxidants studied.Most of the PAHs were oxidized and only < 1% of PAHs volatilized and transferred to the solvent.The removal of PAHs by activated persulfate reached 92%.Modified Fenton reagent could remove 80% ...
