Furfural Removal from Simulated Wastewater Using Zno Nanoparticles / H2O2 in Solar Photocatalysis Reactor

Abstract

Abstract Furfural is aromatic compounds that can cause a significant environmental problem particularly through discharged iindustrial water of oil processing. In this study, the using of the advanced oxidation methods (AOPs) were applied. The results of the experimental work indicated that the degradation of furfural in simulated wastewater and real wastewater from oil refinery was affected by using different concentrations of H2O2, the dosage of nanoparticles of ZnO with nanoscale (36 nm), pH and taking into consideration the effect of the solar radiation intensity with the exposure period. The optimal conditions (H2O2=600mg/l, ZnO NPs=80mg/l, pH=7, Temp=25±5°C and flow rate=50ml/min) at 100mg/l of furfural concentration. Furfural removal efficiency for the type of (APOs) treatment (UVA Photolysis), (UVA/photocatalyst), (UVA/H2O2) and (UVA/H2O2/photocatalyst) were recorded (38%, 55%,68%,96%) respectively after 240 minutes exposure time using simulated wastewater and the rate constant K of furfural degradation was increased at the same conditions (0.0023, 0.0041, 0.006, 0.022) min−1 respectively while for real wastewater from petroleum refinery units, the removal efficiency has been reached to (97.5%) under the same conditions with applied (UVA/H2O2/photocatalyst) option. HPLC was utilized to detect the degradation of the furfural.
