改性Ti/SnO_(2)-Sb电极降解EDTA-Ni电镀废水试验分析

Modifi ed Ti/SnO_(2)-Test Analysis of EDTA-Ni Electroplating Wastewater Degradation by Sb Electrode

为了加强电镀废水中污染物质的降解效果,本文以改性Ti/SnO_(2)-Sb电极为例,详细阐述其在电镀废水EDTA-Ni降解中的操作过程。试验前要合理选择仪器,明确试验制备,并在试验操作过程中详细分析电极寿命、确认电极形态并开展电降解测试。在完成试验操作后,要科学把控还原反应机理、电极表面结构及Ni的去除率,在确保上述内容准确性后获得试验结论,并将改性Ti/SnO_(2)-Sb电极持续作用在电镀废水的降解试验中。

In order to strengthen the degradation effect of electroplating wastewater pollutants,this paper takes the modified Ti/SnO_(2)-Sb electrode as an example to elaborate the operation process in the EDTA-Ni degradation of electroplating wastewater.Before the test,the instrument should be reasonably selected,the test preparation should be specified,and the electrode life should be analyzed,the electrode form and the electrodegradation test should be carried out during the test operation.After the completion of the test operation,the reduction reaction mechanism,electrode surface structure and Ni removal rate should be scientifically controlled to ensure the accuracy of the above content information,and then the test conclusion should be obtained,and the modified Ti/SnO_(2)-Sb electrode is continuously applied in the degradation test of electroplating wastewater.
