活性艳红K-2BP的电化学脱色及能耗分析

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.通过整体电解获得其电化学反应特性,通过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,NaCl浓度为0.2 mol/L、电流密度为60 mA/cm2和室温条件下,30 mg/L的活性艳红K-2BP经电化学降解1 h,脱色率可达94.4%.单位能耗为10 kWh/kg.

The Electrochemical Degradation of reactive brilliant red K-2BP and analysis of Energy Consumption

The electrochemical degradation of reactive brilliant red K-2BP was studied with Pt as the anode and cathode using NaCl as supporting electrolyte.The characteristic of the electrochemical degradation was obtained by the whole electrolysis.Through altering parameters,the efficiency of the electrochemical degradation were also investigated and optimized.It was found that under the optimal reaction conditions(concentration of NaCl 0.2 mol/L and current intensity 60 mA/cm2),the color removal of 94.4% within 1 hour can be obtained.The energy consumption was 0.1 kWh/kg.
