Recently, the activation of chlorine dioxide (ClO2) by metal(oxide) for soil remediation has gained notable attention. However, related mechanisms are still not clear. Herein, variation iron species and ClO2, generated reactive oxygen species, toxicity degradation intermediates were explored evaluated with nanoscale zero-valent (nFe0) being employed to activate ClO2 polycyclic aromatic hydrocarbon (PAH) removal. With an optimized ClO2/nFe0 molar ratio 15:1 a soil/water 3:1, efficiency phenanthrene improved 12% in comparison that ClO2-alone system. The presence nFe0 significantly promoted consumption (improved 85.4%) but restrained ClO2- generation (reduced 22.5%). surface Fe(II) soluble system was 2.0-fold 2.8-fold after 2 min. Electron paramagnetic resonance analysis, along quenching experiments, revealed Fe(IV), HOCl, •OH dominated system, oxidation contributions, respectively, 34.3%, 52.8% 12.9%. PAHs had lower estimated than those lettuces grown ClO2/nFe0-treated displayed better results bioassay indexes ClO2-treated soil. This study offers new perspectives organic-pollutant-contaminated using metal-activated technology.
