Electrocatalytic Degradation of Rhodamine B on the Sb-Doped SnO₂/Ti Electrode in Alkaline Medium.

ABSTRACT: To realize efficient electrocatalytic degradation of organic compounds in alkaline wastewater, an Sb-doped SnO₂/Ti electrode was fabricated and employed for the removal of Rhodamine B (RhB), and the electrocatalytic oxidation performance of this electrode was assessed in an alkaline medium. In an alkaline solution (pH 11), the complete fading of 50 mg·L^-1 RhB could be achieved after 150 min of degradation, the removal efficiency of the chemical oxygen demand reached 56.1% at 300 min, and the degradation process of RhB followed the pseudo-first-order kinetic model very well. Under the attack of hydroxyl radicals, partial RhB was degraded to low-molecular-weight organic acids through N-demethylation and the destruction of the conjugated chromophore. Various techniques i
