Preparation of Ti/Ag+Cu electrode and application on degradation of salicylic acid

采用电沉积法制备了Ti/Ag＋Cu电极并将其用于水杨酸的降解.对含有不同n（Ag）∶n（Cu）的Ti/Ag＋Cu电极的电化学性能进行了研究,考察了支持电解质Na2SO4的浓度对水杨酸降解率的影响,并对超声波降解、电化学氧化降解和声电协同降解效果进行了比较.结果表明：在室温条件下,支持电解质Na2SO4的浓度为1.441 g·L^-1,Ti/Ag＋Cu电极的n（Ag）∶n（Cu）=5∶5时水杨酸的声电协同降解率为99.2%,有很好的协同降解效用.

Ti/Ag＋Cu electrodes were prepared by electrodeposition method and applied in the degradation of salicylic acid. The electrochemical property of the electrodes was studied in detail. The effect of supporting electrolyte concentration of Na_2SO_4 on the degradation rate of salicylic acid was investigated. Degradation of salicylic acid was compared. The results showed that at room temperature, with n（Ag）∶n（Cu） of 5∶5 on Ti/Ag＋Cu electrode and the concentration of Na2SO4（1.441 g·L^-1）, the degradation rate of salicylic acid was 99.2% by synergies of ultrasound and electrochemical oxidation, which exhibited a good synergetic degradation by synergies of ultrasound and electrochemical oxidation.
