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。

关键词: 硫酸盐, 掺硼金刚石, 电活化, 阿特拉津

Abstract:

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 mA/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.

Key words: sulfate, bcoron-doped diamond, electrical activation, atrazine
