恒电流下电生成活性氯降解活性艳红K-2BP

以Pt片作工作电极和辅助电极,NaCl为支持电解质,研究了活性艳红K-2BP的电化学脱色降解行为。通过循环伏安法与整体电解获得其电化学反应特性,经调控溶液的性质考察了不同体系对其降解效果的影响。实验结果表明,在pH为6、NaCl浓度为0.2mol/L、电流密度为60mA/cm2和室温条件下,30mg/L的活性艳红K-2BP经电化学降解1h,脱色率可达94.4%。pH对活性艳红K-2BP的脱色率影响较大,初始pH越小,脱色率越高。

Electro-generated Active Chlorine for Degradation of Brilliant Red K-2BP under Constant Current

Electrochemical degradation of reactive brilliant red K-2BP was studied with Pt as anode and cathode using NaCl as supporting electrolyte.Characteristics of electrochemical degradation were obtained by cyclic voltammetry and whole electrolysis.Parameters altering the efficiency of electrochemical degradation were also investigated and optimized.It was found that under the optimal reaction conditions of pH 6,concentration of NaCl 0.2mol/L and current intensity 60mA/cm2, color removal of 94.4% within 1h can b...
