Abstract

The oil tanks of gas station and petrochemical industry are installed underg round, and the BTEX in the oil might affect the soil and underground water seriously and pose a threat to the neighbourhoods. Fenton-like oxidation is derived from in situ chemical oxidation remediation of soil and underground water. Catalysis of H2O2 by iron based materials produces free radicals which could destroy the organic pollutants in soils and underground water therefore reduces their toxicity level and mineralize them to H2 O and CO2. By having advantag es such as low cos t, accessible and non-toxic, Fenton-like oxidation have great potential in development. This study synthesizes iron based materials and apply to Fenton-like oxidation, then utilized Fenton-like reaction to treat benzene and MTBE pollutants. The results show the optimal operation condition of IBM (Iron-based material, IBM) is 250 g/L, H2O2 concentration is 23.52 mM. With natural pH and 4 hours reaction time, the removal efficiency of IBM (A) and IBM (B) to Benzene is 65% and 55%, respectively. And the removal efficiency to MTBE is 47% and 33%. By Fenton-like reaction, IBM (A) and IBM (B) has the potential to be used as the material for permeable reactive barrier to treat Benzene and MTBE pollutants.
