Key Points

The research aims to assess how effectively levofloxacin is removed from water using different adsorbents.
Evaluated the adsorption kinetics of levofloxacin by Cu–Fe layered double hydroxides and mixed oxides.
Analyzed adsorption isotherms to understand how levofloxacin interacts with the adsorbents.
Investigated the mechanisms of adsorption and energy efficiency of the processes.
Proposed the green valorization of waste materials as viable adsorbents.
Both Cu–Fe layered double hydroxides and mixed oxides showed significant adsorption of levofloxacin.
The results indicate that layered double hydroxides have a higher adsorption capacity compared to mixed oxides.
Kinetic studies revealed rapid adsorption initially, followed by slower uptake over time.
