%X The performance and technical parameters of Fenton treatment of 2,4-and 2,6-dinitrotoluene(DNT)in soil contaminated with explosive compounds has been investigated at laboratory scale.The experimental results showed that 2,4-and 2,6-DNT were removed completely in two hours while 87% of COD was removed in eight hours.The optimal H2O2 concentration was 26.46mmol,corresponding to a FeSO4:H2O2 mole ratio of 1:36.78~73.56.Much better removal performance can be achieved by Fenton oxidation treatment of washing-out liquid than by direct oxidation of contaminated soil on a column.Based on kinetic analysis and acetone inhibition assays,it was concluded that Fenton oxidation of 2,4-DNT is easier than oxidation of 2,6-DNT.GC-MS analysis showed that not only 2,4-DNT and 2,6-DNT but also other nitroaromatic organic compounds were totally removed during Fenton oxidation treatment.
