Microwave-assisted Fenton degradation of methylene blue

This work experimentally determined the effect of combining of microwave irradiation and the Fenton process on decolorization of methylene blue (C16 H18 N3 SCl, MB). As [H2O2] increased from 2.65 to 4.41 mM, the decolorization of MB increased from 22.7 to 99.1%. As [Fe2+] increased from 0.07 to 0.18 mM, the decolorization of MB increased from 24.0 to 98.5%. MB removal efficiencies were ≥ 95% at [H2O2 ] ≥ 3.5 mM and 3.5 ≤ [H2O2 ]/[Fe2+] ≤ 17.3, but [H2O2 ]/[Fe2+] ≥ 20 caused a decrease in MB removal. A two-stage kinetic model matched the experimental data well.
