%X This paper describes the character of the reduction of TNR by ZVI in anaerobic conditions and the oxidative reaction of amine resorcine in the system of ZVI-EDTA-O2. The products of TNR by ZVI in anaerobic conditions were amine resorcine compounds. These compounds tend to be easier to oxidize by the generated in the system of ZVI-EDTA-O2. HPLC and Chemical Oxygen Demand analysis (COD) were used to monitor the efficiency of reactions. The experiments have suggested that the removal of TNR from groundwater should be implemented by a two step process. The first step is reduction of TNR by ZVI to form amine resorcine. The second step is oxidation of amine resorcine in a system consisting of ZVI-EDTA-O2. From the obtained results, a model for TNR contaminated groundwater treatment has been suggested and tested.
