AI Technical Summary
Existing technologies are insufficient for efficiently degrading polycyclic aromatic hydrocarbons in organically polluted soils, especially in aging soils where oxidants are difficult to effectively degrade. Furthermore, traditional remediation methods are characterized by high costs, soil toxicity, or low efficiency.
A remediation material using manganese dioxide-supported biochar coupled with chlorine dioxide is employed. Biochar provides a large number of active sites and a high specific surface area, while manganese dioxide nanoclusters activate chlorine dioxide to generate free radicals, thereby achieving efficient oxidative degradation of polycyclic aromatic hydrocarbons.
It significantly improves the degradation efficiency of polycyclic aromatic hydrocarbons, reduces the amount of oxidant used, and minimizes the negative impact on soil. It has the advantages of low cost, short cycle, and wide applicability.
