Photodegradation under UV Light Irradiation of Various Types and Systems of Organic Pollutants in the Presence of a Performant BiPO4 Photocatalyst

In this study, we prepared spheroid microstructures of monoclinic bismuth phosphate BiPO4 by a facile solid-state reaction at 500 °C. The crystal structure was refined using the Rietveld method, where cell resolved system (parameters a, b, c, β) with space group P21/n. SEM images showed that solid catalyst presented homogeneous morphologies. These microparticles (BiP-500) have been used as photocatalysts to photodegrade, under UV light irradiation, three cationic dyes (Rhodamine B, RhB; Methylene Blue, MB; and Toluidine TB), anionic (Congo Red, CR; Orange G, OG; Methyl Orange, MO) mixtures RhB-MB, RhB-OG MO-OG organic dyes. photodegradation efficiency these BiP-500 is found be optimal in case RhB solutions, RhB-MB binary mixtures. shows high selectivity for conversion mixture into CO2 H2O. Total carbon analysis an dye (RhB, OG RhB-MB) confirms mineralization pollutants presence particles. photocatalytic our photocatalyst has confirmed, view facilitate applications field depollution wastewater agricultural environment degradation parathion-methyl (PM) pollutant.
