Polycyclic aromatic hydrocarbon contaminated soil remediation effect evaluation method and detection kit

The invention provides a method for detecting polycyclic aromatic hydrocarbon pollutants in soil. The method comprises the following steps of: S1, adding an extractant into a soil sample, performing concentrating, and fixing the volume to obtain a to-be-detected sample solution; and S2, adding the to-be-detected sample solution into a mixed solution of formaldehyde and concentrated sulfuric acid,observing a reaction result, and comparing the reaction result with reaction results of polycyclic aromatic hydrocarbon standard substance solutions with different concentrations and the mixed solution of formaldehyde and concentrated sulfuric acid to obtain the concentration of polycyclic aromatic hydrocarbon in the soil. the invention further provides a kit for polycyclic aromatic hydrocarbon detection. The method and the kit are adopted for polycyclic aromatic hydrocarbon concentration detection of the soil; detection can be completed through visual comparison; operation is easy; consumed time is short; cost is low
