Two-dimensional Ti₃C₂T_x MXene nanosheets intercalated with sodium ions (SI-Ti₃C₂T_x) was synthesized by a facile batch fabrication method and applied for Ciprofloxacin (CPX) removal in the adsorption and electrochemical regeneration process. The successful synthesis and properties of the synthesized nanosheets were evaluated with X-ray diffraction (XRD), FE-scanning electron microscopy (SEM), FE-transmission electron spectroscopy, Zeta-potential analyses, and X-ray photoelectron spectroscopy. After intercalation, the surface terminations and the spacing between the layers of SI-Ti₃C₂T_x MXene were increased which enhanced the adsorption capacity of nanosheets in terms of fast kinetics and higher removal rates. As a result, 10 mg L⁻¹ CPX was reduced to approximately 1 mg L⁻¹ in just 15–20 min, which is an extraordinary kinetic behavior in CPX adsorption. Elovich kinetic model and the Redlich …
