摘要: The effects of ultrasonic irradiation, the chelating agent modified Fenton reaction, and a combination ultrasound method in removing petroleum contaminants from soil were studied. results showed that contaminant removal rate treatment combined with an oxalic acid chelating agent was 55.6 % higher than without agent. average using ultrasound–Fenton 59.0 % treatment. A Fe2+/Fe3+-oxalate complex–modified reagent resulted significantly rates n-alkanes (CnH2n+2, n < 28), isoprenoid hydrocarbons, aromatic saturated polycyclic terpenes compared alone or method. reaction can unselectively remove multiple components residual hydrocarbons number benzene rings hydrocarbons. chemistry heterocyclic compounds position substituents affect degradation process.
