Description
Summary:2D-Ti C T MXene nanosheets intercalated with sodium ions (SI-Ti C T ) were synthesized and utilized in simultaneous adsorption and electrochemical regeneration with ciprofloxacin (CPX). The primary focus of this study is to investigate the long-term stability of SI-Ti3C2Tx MXene and to propose the underlying regeneration mechanisms. The successful synthesis of Ti AlC , Ti C T MXene, and SI-Ti C T MXene was confirmed using X-ray diffraction, X-ray photoelectron spectroscopy, and Raman spectroscopy. Electrochemical regeneration parameters such as charge passed, regeneration time, current density, and electrolyte composition were optimized with values of 787.5 C g , 7.5 min, 10 mA cm , and 2.5w/v% sodium chloride, respectively, enabling the complete regeneration of the SI-Ti C T MXene. In addition, the electrochemical regeneration significantly enhanced CPX removal from the SI-Ti C T MXene owing to partial amorphization, disorderliness, increased functional groups, delamination, and defect creation in the structure. Thus, the synthesized nano-adsorbent has proven helpful in practical water treatment with optimized electrochemical regeneration processes.
