High-molecular Weight polycyclic aromatic hydrocarbons which have high molecular weight and stable structure are difficult to be removed. In this study, using different oxidations to oxidate the High-molecular Weight polycyclic aromatic hydrocarbons include Ba A, Bb F, Ba P, IPY, DBA, in soil samples which are taken from contaminated soil in Jing-jin-ji district. The result show that typical oxidations including sodium hypochlorite, hydrogen peroxide, sodium persulfate, Potassium Permanganate have different effects in High-molecular Weight polycyclic aromatic hydrocarbons removal. Then the method to strengthen its ability of oxidation is explored. The result show that the PAHs removal rate have improved though the oxidation advanced. The suitable concentration of advanced oxidation is sodium persulfate: 10 g/L; ferrous sulfate: 1 g/L, citric acid: 0. 1 g/L. The conclusion can be used as a reference for the oxidation treatment of High-molecular Weight polycyclic aromatic hydrocarbons.
