Three kinds of oxidants,hydrogen peroxide-ferrous sulfate,sodium persulfate activated by calci-um oxide and sodium persulfate activated by sodium hydroxide,were selected to treat petroleum hydrocarbons(Cl0～C40)contaminated soil.Comparing the treatment effect,a good oxidant was selected for the remediation of petroleum hydrocarbons(Cl0～C40)contaminated soil by ectopic chemical oxidation.The results indicated that so-dium persulfate activated by sodium hydroxide could efficiently and stably degrade petroleum hydrocarbons(C10～C40)in soil.When the addition of sodium persulfate was 5％,the highest degradation rate of petroleum hy-drocarbon(C10～C40)was 83.4％.The content of petroleum hydrocarbon(C10～C40)in the contaminated soil af-ter treatment met the standard requirement with the adding of 2％sodium persulfate.
