Fenton Oxidation of 2, 4, 6-Trinitrotoluene in Contaminated Soil Slurries

摘要

Numerous acres of soil are contaminated with trinitrotoluene (TNT) at sites where munitions were formerly manufactured, stored, or demilitarized. Our objective was to determine the potential for remediating TNT-contaminated soil by direct Fenton oxidation of contaminated soil slurries. The Fenton reagent (Fe~2+ + H_2O_2) effectively oxidized TNT in a soil slurry (1:5 w/v soil:H_2O) contain- Ing 4200 mg TNT kg~-1, but TNT destruction was affected by temperature, dissolved organic mat- Ter (DOM), and clay mineralogy.
