Heterogeneous Fenton Oxidation of H Acid in Water by Nanometer Zero-Valent Iron


Nanometer zero-valent iron (NZVI) was prepared as the heterogeneous Fenton catalyst. The degradation of H-acid was investigated by heterogeneous Fenton-like oxidation. The influence of reaction time, amounts of H2O2, dosage of NZVI, solution pH and concentration of coexisting ions was investigated on degradation of H-acid by heterogeneous Fenton-like oxidation. The optimum conditions were obtained to be 60 min of reaction time, dosage of NZVI 0.03 g/L, solution pH of 3 and H2O2 amount of 80 mg/L for a H-acid concentration of 50 mg/L with a removal of 99.3%. The presence of sodium chloride and sodium sulfate hardly had a inhibition on H acid degradation.
