摘要 用掺硼金刚石(BDD)电极对硫酸盐进行阳极活化,结果发现,在循环阳极电极模式下,BDD阳极电活化硫酸盐去除阿特拉津(ATZ)的速率较直接电解去除ATZ的速率高出约14倍。当电流密度为30 mA/cm2、Na2SO4电解质浓度为0.1 mol/L时,电活化硫酸盐产生的SO4·-对ATZ降解的相对贡献率可达90%以上。 Boron-doped diamond(BDD)electrode was used for anode activation of sulfate.The results showed that in the cycle anode electrode mode,the rate of atrazine(ATZ)degradation by electro-activated sulfate was about 14 times higher than the rate of ATZ degradation by direct electrolysis.When the current density was 30 m A/cm2 and the Na2SO4 electrolyte concentration was 0.1 mol/L,the SO4·-produced by electro-activated sulfate could contribute more than 90%to the degradation of ATZ.
