Abstract

The study presents the development of a novel magnetic g-C3N4/MXene nano-photocatalyst for the efficient removal of pharmaceutical azithromycin from real wastewater. The escalating levels of pharmaceutical pollutants, particularly azithromycin, necessitate robust removal techniques. Photocatalysis, known for its affordability and eco-friendliness, is explored here, focusing on combining g-C3N4 with 2D MXene, offering stability, light absorption, and magnetic properties. The synthesis and characterization methods confirm the structural integrity and successful production of the nano-photocatalyst. High-performance liquid chromatography measures azithromycin levels in actual wastewater. Under sunlight exposure, the nano-photocatalyst exhibits exceptional photodegradation, removing 94% of azithromycin in just 120 min. Kinetic studies reveal pseudo-second-order kinetics and significant organic carbon removal efficiency exceeding 85% in less than 90 min is observed. Overall, the research highlights the potential of the magnetic g-C3N4/MXene nano-photocatalyst for sustainable and effective pharmaceutical contaminant remediation, positioning it as a promising solution for water treatment processes.
