Abstract：The Fe/C catalyst was prepared by impregnation method using activated carbon as supporter and was used as a heterogeneous Fenton catalyst for degradation of simulated N,N-Dimethylformamide (DMF) solution. The effects of initial pH value, H2O2 dosage, catalyst dosage and reaction temperature on DMF removal rate were investigated. The results showed that, under the optimal conditions of initial pH value 2.5, H2O2 dosage 3.0 g/L, catalyst dosage 6.0 g/L and reaction temperature 30 ℃, for 1 000 mg/L DMF solution, the chemical oxygen demand(COD) removal rate was above 60% with lower iron concentration 0.7 mg/L in 60 min. The catalyst had good stability and could be recycled. After 5 runs, the COD removal rate of 45.3% could still be achieved in 60 min.
