The sonoelectrochemical degradation of triclosan in aqueous solutions with high-frequency ultrasound (850kHz) and various electrodes was investigated. Diamond coated niobium electrode showed the best results and was used as standard electrode, leading to effective degradation and positive synergistic effect. The influence of different parameters on the degradation degree and energy efficiency were evaluated and favorable reaction conditions were found. It could be shown that 92% of triclosan (1mgL(-1) aqueous solution) was degraded within 15min, following pseudo-first order kinetics.
采用高频超声（850kHz）和各种电极对水溶液中的三氯生进行了声电化学降解研究。涂覆金刚石的铌电极表现出最佳效果，被用作标准电极，实现了有效降解和正协同效应。评估了不同参数对降解程度和能量效率的影响，找到了有利的反应条件。结果表明，在 15min 内，浓度为 1mg/L 的三氯生（水溶液）降解率达到 92%，遵循准一级动力学。
