Abstract
The elimination of organic pollutants from water poses a considerable challenge in environmental remediation in this study, the potential of ZnS-ZnO semiconductors as efficient photocatalysts for degrading aqueous solutions of ceftriaxone (CEF) was investigated in a mini-UV reactor. The ZnS-ZnO heterostructures were synthesized via the hydrothermal method and characterized using analytical techniques (SEM, FTIR), demonstrating considerable photocatalytic activity (UV-Vis monitoring), with degradation of CEF occurring within a relatively short period of time.
Keywords: ceftriaxone, degradation, photocatalysis, ZnS - ZnO
