We report the sonoelectrochemical degradation of ciprofloxacin in water using BaTiO₃ supported on a titanium sheet electrode (Ti/BaTiO₃). BaTiO₃ nanoparticle was synthesized and characterized with X-ray diffractometer (XRD), field emission scanning electron microscopy (FESEM) and energy-dispersive X-ray spectrometer (EDS). Ti/BaTiO₃ electrode was fabricated by drop-drying a slurry of BaTiO₃ on an etched titanium sheet. Electrochemical techniques such as cyclic voltammetry (CV), chronoamperometry (CA), linear sweep voltammetry (LSV) and electrochemical impedance spectroscopy (EIS) were used to determine the current response as a function of the induced polarization within the BaTiO₃ crystal. The sonocurrent response of the electrode was improved and the impedance was lowered as the applied ultrasound power was increased from 20 W to 40 W. The application of the fabricated electrode for sonoelectrochemical (SEC) degradation of ciprofloxacin in synthetic and real wastewater samples were carried out for 180 min. A degradation efficiency of 68.42% was at 40 W ultrasound power, 2.0 V bias potential and 10 mm electrode-probe distance. Furthermore, the mineralization percentages of 49.63% and 30.74% were obtained for total organic carbon removal in synthetic wastewater and real wastewater, respectively. A positive synergy obtained reveals that Ti/BaTiO₃ electrode is effective and suitable for sonoelectrochemical removal of pharmaceutical pollutants in water.
