| Abstract: | An enclosed reactor was used to evaluate Fenton reagent,modified Fenton reagent,potassium permanganate and activated persulfate for removal of benzene,toluene,ethyl benzene,and xylene(BTEX) from soil at contaminated industrial coking sites.The results showed that Fenton reagent and modified Fenton reagent were the optimum oxidants for removing BTEX,and these oxidants decreased the concentration of BTEX in soils by 83 % and 73 %,respectively.The proportion of BTEX volatilized from the soil was < 4% in both c... |
