Abstract:
The aim of this study was to investigate the PAHs removal efficiency in coking plant contaminated soil when disposed by different oxidants with different dosages (hydrogen peroxide, Fenton’s reagent, modified Fenton’s reagent, potassium permanganate, activated sodium persulfate) and the PAHs distribution characteristics in removing parts, soil residue parts, recycling parts and supernate after oxidation reactions. Analyzed the variation characteristics of soil properties (pH and soil temperature) when used different oxidants in oxidation reactions process, screened out the effective and safe remediation oxidants. The research results indicated that the potassium permanganate has the best remediation ability and undemanding reaction conditions than other oxidants. The contaminant which be volatilized into surrounding environment was rarely when disposed by potassium permanganate in remediation process. Consequently, selecting potassium permanganate as remediation oxidant to treat PAHs in coking plant contaminated soils was the best choice.
