( B 4 C /C)‐β‐ PbO 2 electrodes were prepared by high‐pressure molding technique and characterized by X‐ray diffraction, scanning electron microscopy, polarization curves, cyclic voltammetry curves, and corrosion resistance test. In this paper, the effects of initial concentration, current density, electrolyte concentration, pH , and electrode spacing on tetracycline hydrochloride ( TCH ) degradation were investigated. Results indicated that modified electrode had high electrochemical activities, high oxygen evolution potential, and excellent corrosion resistance. The maximum removal rate of TCH could reach 90.87% at initial concentration of 300 mg/L after 120 min electrolysis with Na 2 SO 4 concentration of 0.2 mol/L, electrode spacing of 1 cm, current density of 30 mA /cm 2 , and pH 3. Pseudo‐first‐order kinetics equation was followed during electrocatalytic degradation of TCH with 20%( B 4 C /C)‐β‐ PbO 2 electrode.
