电芬顿体系C@Fe泡沫复合阴极制备及邻苯二甲酸二甲酯降解研究

Preparation of C@Fe Cathode and its and Application for Electro-Fenton Degradation Dimethyl Phthalate

阴极电芬顿体系可以高效降解有机污染物,阴极材料是其核心器件。本研究将酚醛树脂原位合成包覆于泡沫铁材料上经高温煅烧碳化。将其应用于电芬顿体系降解邻苯二甲酸二甲酯(DMP),在施加恒电流80mA,曝气量100ml/min的最适条件下,120min内50mg/L DMP可完全降解,180min时TOC去除率90.54%,且循环使用3次稳定性良好。

The organic pollutants can be effectively degraded by the Cathode Electro-Fenton system.The cathode material is the core device.In this study,phenolic resin was synthesized and coated on foam iron material,and then carbonized at 900℃。It was applied to the degradation of dimethyl phthalate (DMP) in the electro-Fenton system.Under the optimum conditions of 80 mA and 100 ml / min aeration,50 mg / L DMP could be completely degraded in 120 min.the TOC removal rate was 90.54% in 180 min,and the recycling stability was good.
