In the present study, Ti/SnO2-Sb/NSGCN-PbO2 electrode was fabricated by electrodeposition technique. The field emission scanning electron microscopy (FESEM) coupled to an energy dispersive X-ray (EDX) spectrometer, X-ray diffraction (XRD), linear scanning voltammetry (LSV), cyclic voltammetry (CV), chronopotentiometry (CP) and chronoamperometry (CA) analyzes were used to examine the surface morphology, the elemental composition analysis and electrochemical properties of the electrode. The findings showed that the Ti/SnO2-Sb/NSGCN-PbO2 electrode has a finer particles, a more compact and uniform structure, a higher potential for oxygen evolution, a smaller charge transfer resistance, a good current density and a more desirable electrode stability. In this study, the Ti/SnO2-Sb/NSGCN-PbO2 electrode performance in ciprofloxacin (CIP) removal was investigated. Electrochemical removal of CIP was done via anodic oxidation method by using generate hydroxyl radical (OH֯) on the anode surface. The removal efficiency of ciprofloxacin in 240 minutes at pH=6.8 and ambient temperature was 44.3%.Furthermore the amount of energy consumed was 0.368 kWh m-3. According to the obtained results Ti/SnO2-Sb/NSGCN-PbO2 anode performs better than Ti/SnO2-Sb/PbO2, Ti/PbO2 and Ti/SnO2-Sb in removing Ciprofloxacin and energy consumption.
