摘要/Abstract

摘要： 将催化裂解法制得的碳纳米管,先经稀酸分散和空气热氧化处理,再按一定比例加入酚醛树脂,高速球磨处理后,将碳纳米管电极片热压成型.其表面形貌由扫描电镜(SEM)表征.以碳纳米管电催化电极作阳极,不锈钢片为阴极,降解处理含活性艳红X-3B模拟印染废水.考察了电流密度、电解质浓度、体系反应温度及pH值对废水降解效率的影响.结果表明:酸性条件下有利于染料有机物降解反应的进行,于常温下即可作高效降解处理.

Abstract: The catalytic splitting decomposition of carbon nanotubes isprocessed by dispersing with dilute nitric acid and thermal oxidation. Then well-proportionedphenolic resin is mixed in the carbon nanotubes. Then, the carbon nanotubesare made into electrodes by hot-press molding after the process of milling with high speed. The surface of the carbon nanotubes electrodes is analyzed by SEM. Active red X-3B simulated waster water is disposed by carbon nanotubes catalyticelectrode (anode) and stainless steel(cathode). The influencing factors of degradation by current density, concentrationof electrolyte, systemtemperature and pH are investigated. The experimental results indicated that acidiccondition is propitious tothe degradationreaction of organicdyestuff and wastewater can be disposed at normal temperature.
