Pharmaceutical residues in aquatic environments have the potential to induce bacterial resistance, subsequently complicating disease treatment Magazine Rack and posing a substantial hazard to public health.This study demonstrates the production of carbon dots from Cassia fistula flowers using a hydrothermal process.The obtained carbon dots were then mixed with zinc oxide to create CDs@ZnO-H400.This heterojunction photocatalyst exhibited notable enhancement in photocatalytic performance due to improved charge separation efficiency at the interface.The CDs@ZnO-H400 catalyst effectively removed two medications, ciprofloxacin and paracetamol.

Ciprofloxacin showed maximum photocatalytic efficiency, with 99.8 % degradation, while Dryer Door Catch Cover paracetamol exhibited a degradation efficiency of 75.1 %.The stability of the synthesized photocatalyst was evaluated across four usage cycles using EDX-SEM, FTIR, and XRD techniques.The CDs@ZnO-H400 heterostructure photocatalyst maintained strong photoactivity even after the fourth cycle of usage.
