Abstract: Batch experiments were conducted to examine the adaptability of catalytic material zeotileartificial pillared by α-FeOOH (ZPF) using as fill-in material in the permeable reactive barrier (PRB) system. The concentration of Fe iron and the degradation of 2, 4-DNT in three circulating experiments using ZPF as catalyst were determined. Then, the ZPF filtrated and collected from the reaction solution was characterized by FTIR. The results demonstrated that the degradation of 2,4-DNT was ultimately stable in the ZPF-H₂O₂ reaction system, and the degradation rate was 48.2%, 43.3%, and 44.6%, respectively. The concentration of Fe ions maintained at low levels, and especially under neutral and alkaline conditions it was less than 0.3 mg/L, thus without changeable structure and secondary pollution toward the groundwater environment. ZPF could be used to repair such pollutants as nitrobenzene in the underground through catalytic oxidation.
