Rare earth ytterbium-doped tin-antimony (Ti/SnO_2-Sb-Yb) was used as the anode to catalyze the oxidation of pyridine wastewater, and the elfects of five parameters, including current density, electrolyte concentration, electrode spacing, pH, and initial pyridine concentration, on the degradation of pyridine were discussed. The reaction kinetics and energy consumption of pyridine degradation were analyzed. The results showed that the removal rates of pyridine and TOC were 96.8% and 85.62%, respectively , after reaction under the optimal conditions for 50 min. Under this reaction system, the degradation of pyridine confommed to pseudo-first-order kineties. The doping of Yb increased the apparentrate constant and apparent mass transfer coefficient in the reaction system by 100%, and reduces the energy consumption by 23%.
