Degradation of endocrine disruptor atrazine by electrocatalytic oxidation

Abstract:

To find a new effective method of degradation of atrazine,the degradation was studied by electrocatalytic oxidation of atrazine in water,and Sb doped Ti/SnO2 electrode was used as anode and stainless steel plate as cathode.The main influencing factors and degradation pathway of atrazine were discussed.Results showed that when current density was 200 A/m2,initial concentration of atrazine was 10 mg/L and pH value was 6.97,100% atrazine was removed within 30 min.Meanwhile,power consumption was only 6.67×10-2 kWh/g.The primary degradation process is dealkylation,dechlorinationa and alkylic-oxidation,and a series of intermediate products such as OHA,DAA,ANE were produced during the process of electrocatalytic oxidation of atrazine.The results suggest that electrocatalytic oxidation method can be cost-effective removal atrazine.
