文章摘要:Fe-ZSM-5 molecular sieve catalysts were fabricated and characterized through scanning
electron microscopy, energy dispersive spectroscopy, and X-ray diffraction techniques.
Researches were developed within a heterogeneous Fenton-like catalysis system established
with Fe-ZSM-5 molecular sieve catalyst and H2O2, with regard to the effects of pH, H2O2
dosage, inlet concentration of aniline, and catalyst dosage on extent of removal and reaction
rate, and preliminarily revealed the mechanisms of degradation in aniline wastewater. Outcomes
have demonstrated that Fenton-like Fe-ZSM-5 molecular sieve catalysts are functionally
stable and recyclable in which the extents of removal of aniline, CODCr and TOC are
96.4, 92.5, and 72.5%, respectively; with 3 g catalyst dosed into 500 mL aniline wastewater
of 200 mg L−1 in concentration, pH 4, and H2O2 of 0.5Qth (0.31 mL L−1), the Fenton-like conditions
could not only break up the inner structures of aniline, but also catalyze the products
in further mineralization to CO2 and H2O.
