Abstract
A method for degrading halogenated polycyclic aromatic hydrocarbons in soil by using cryptomelane, relating to the technical field of soil regeneration, includes the following steps: S1: preparing cryptomelane; and S2: degrading halogenated polycyclic aromatic hydrocarbons in soil, where S2 includes S2-1: taking a soil sample, and grinding and removing impurities; S2-2: adding solid cryptomelane prepared in Step S1 in the soil sample, uniformly mixing to obtain a mixture, and transferring the mixture to a shaker for oscillation, thus obtaining a soil sample containing cryptomelane; S2-3: transferring the soil sample containing cryptomelane into a brown glass bottle, adding a halogenated polycyclic aromatic hydrocarbon methanol solution into the soil sample for continuous oscillation, and then degrading the soil sample containing cryptomelane at a room temperature.
