ANALYSIS OF ELECTROCHEMICAL DEGRADATION OF COKING WASTEWATER USING MULTIWALL CARBON NANOTUBES MODIFIED ELECTRODE

摘要：

A modified electrode coating with admixture of multi-walled carbon nanotubes and PTFE was used to treat the coking wastewater after biological purification. UV-VIS, GC/MS and COD measurement were used to observe the change of organic compositions in wastewater. The degrading efficiency of the prepared electrode was compared with that of the IrSnSb/Ti electrode. The results showed that after electrochemical degradation by MWNT-ME for 2 hours, the number of organic pollutants in coking wastewater reduced from 107 to 49, and COD was reduced by 51％. Compared with IrSnSb/Ti electrode, MWCNT-ME showed better electrochemical reactivity. electrochemical oxidation is the major fact of the degradation of organic pollutants during the electrolyzing of coking wastewater.
