Decolorization of methyl orange solution catalyzed by fly ash-H2O2 under microwave irradiation

Abstract

This study explored the potential use of fly ash from coal as a heterogeneous catalyst in the degradation of azo dye by using H2O2 irradiated by microwave. The effects of various parameters such as fly ash loading, temperature, pH, initial concentration of methyl orange, and dosage of H2O2, and deactivation of catalytic effect of fly ash were studied.
