Metronidazole (MZ) and penicillin G (PG) are antibiotics frequently detected in aqueous systems as pollutants. Their presence water is a global challenge requiring the development of sustainable solutions for purification. Therefore, this study synthesized improved adsorption performance chromium ferrite (CrFe2O4) via incorporation metal-organic framework (MOF-5) to produce CrFe2O4@MOF-5 composite. CrFe2O4 were characterized using series analytical instrument. Both adsorbents exhibited four-phase mass loss from thermogravimetric analysis, while Brunauer-Emmett-Teller (BET) results gave surface area 40.94 m² g- 1 59.76 CrFe2O4@MOF-5. Interestingly, microscopical images unfolded surfaces be heterogeneous, elemental mapping confirmed constituent elements Cr, Fe, O, C Zn. higher affinity (91.67 mg 1) PG than (53.82 1). Similarly, was better (90.24 compared (50.41 towards MZ. Freundlich Langmuir isotherm may describe removal process MZ by sorption fitted best mechanism involving electrostatic interaction pore diffusion. The its regeneration capacity agreeably with most published literature. This current showed potential adsorbent decontaminating PG-polluted systems.
