Abstract

This work experimentally determined the effect of combining of microwave irradiation and the Fenton process on decolorization of methylene blue ($C_{16}H_{18}N_3SCl$, MB). As [$H_2O_2$] increased from 2.65 to 4.41 mM, the decolorization of MB increased from 22.7 to 99.1%. As [$Fe^{2+}$] increased from 0.07 to 0.18 mM, the decolorization of MB increased from 24.0 to 98.5%. MB removal efficiencies were ${\geq}95%$ at $[H_2O_2]{\geq}3.5mM$ and $3.5{\leq}[H_2O_2]/[Fe^{2+}]{\leq}17.3$, but $[H_2O_2]/[Fe^{2+}]{\geq}20$ caused a decrease in MB removal. A two-stage kinetic model matched the experimental data well.
