Abstract: A modified Fenton reagent system was founded with sodium iron EDTA as a catalyzer, and influencing factors, effects and control parameters of decontamination of soil containing phenol by this modified Fenton reagent were studied. The results showed that the removal efficiency of phenol (initial content is 2 mg/g) in soil was over 90% under optimal operating conditions: 30% H2O2 of 0.05 mg/g, sodium iron EDTA of 2 μmol/g,system moisture content of 33%, and reaction time of 1 h. The ending pH value of soil was about 5.70. It makes the later treatment much easier. The process could oxidize high content of phenol contained in hazardous waste quickly, safely and efficiently.
