| Abstract: |
An efficient and convenient method for
degradation of Acid orange 3 (AO3) dye from aqueous solution by combination of Fly ash/H2O2
and ultrasound irradiation is reported. The effects of
the relevant operating conditions
(pH value, dye concentration, H2O2
concentration, dosage of Fly ash and different reaction system) on the
degradation of AO3 were also observed. The combination method was found to be
effective and could yield better results than either sonolysis or Fenton-like
oxidation individually. Removal of 96% was obtained under the optimum
conditions
(dye concentration, 100 mg/L; H2O2, 5.4 mM; Fly ash,
2.5 g/L; pH 3, ultrasonic
irradiation frequency of 25 kHz, room temperature). The process of the degradation
follows Behnajady’s kinetic mathematical model.
