Reductive Transformation of p-Nitrophenol by the Effect of the Low Crystalline γ-FeOOH and Oxalic Acid

Article Preview

Abstract:

Low Lepidocrocite (γ-FeOOH) was synthesized with air oxidation method. In anaerobic conditions, the reductive transformation of p-nitrophenol (p-NP) was investigated with the low crystalline γ-FeOOH as catalyst in the presence of oxalic acid. Results showed that the oxalic acid could effectively promoted the reduction of p-NP, the optimal concentration for the oxalic acid was 2.0 mM. The surface bound Fe (II) concentration of γ-FeOOH was indirectly detected, which showed reductive transformation mainly referred to Fe (II) mechanism.
