为给电极的制备及水杨酸的降解提供一定理论依据,采用电沉积法制备了Ni基Ag-Cu合金电极并应用于水杨酸的降解过程.对不同Ag-Cu物质的量比例的Ni基Ag-Cu合金电极的电化学性能进行了考察,探索了在板间距、外加电压、电解时间等试验条件相同时,不同电解液浓度对水杨酸降解率的影响,比较了电化学氧化降解和声电协同降解效果.结果 表明:在温度、电流密度、电极间距、电极材料等试验条件相同,当电沉积液nAg∶nCu=8∶2时,Ni基Ag-Cu合金电极表面形貌良好,对水杨酸的降解率最高.Na2SO4作为电解质时最佳电解液浓度为1.064 g/L,此时对水杨酸的电化学氧化降解率为98.01％,而声电协同降解率为99.89％,协同效应下降解完全程度更高.
