Photocatalytic Azo Dye Degradation Using Graphite Carbon Nitride Photocatalyst and UV-A Irradiation

The photocatalytic degradation of Acid Red 26 was examined utilizing a graphitic carbon nitride (g-C3N4) catalyst and UV-A light in this study. We investigated how successfully the approach removed from synthetic actual municipal wastewater. Both aqueous matrices allowed for extremely high clearance rates. Wastewater degraded at slower rate than other matrices, might be ascribed to wastewater’s complicated chemical composition. Using liquid chromatography-mass spectrometry (LC-MS), IPs both effluent were determined. mechanisms are hypothesised comprise oxidation, dealkylation, methoxy group cleavage based on observed intermediate products (IPs). proven scavengers, we also able investigate role reactive species process illustrate significance h+ O2• reaction. Chlorococcum sp. Dunaliella tertiolecta microalgae utilised assess development ecotoxicity. low toxicity throughout when clean water used as matrix, with no production hazardous IPs. In case wastewater, there an early rise toxicity, which scientists believe caused by matrix’s make-up. To lower heterogeneous photocatalysis used, end treatment, nearly full detoxification obtained.
