Abstract

The present study investigates the fabrication of carbon aerogel, utilising corn stover as a primary constituent by employing the freeze-drying-carbonization method for the purpose of modifying cathode materials for the electro-Fenton method. The experimental study investigated the removal of a pharmaceutical substance, roxithromycin, using carbonation temperature and current intensity as the independent variables. The research findings demonstrated that carbon aerogel electrodes, subjected to different carbonization temperatures, possess a distinctive three-dimensional mesh architecture. Furthermore, it was observed that both the degree of graphitization and the presence of unsaturated carbon structures within the material intensified as the carbonization temperature was elevated. Under optimal experimental conditions (10 mA/cm2 electrical density and 600℃ carbonisation temperature), the removal rate of roxithromycin reached 75.06%. This research offers innovative concepts and techniques for harnessing organic remediation using the electro-Fenton process.

生物质炭气凝胶修饰阴极电fenton法高效去除水中罗红霉素

本研究以玉米秸秆为主要原料，采用冷冻干燥-碳化法制备碳气凝胶，用于电芬顿法修饰正极材料。以碳化温度和电流强度为自变量，对罗红霉素的脱除进行了实验研究。研究结果表明，在不同的碳化温度下，碳气凝胶电极具有独特的三维网状结构。此外，随着炭化温度的升高，材料的石墨化程度和不饱和碳结构的存在都增强了。在最佳实验条件（电密度为10 mA/cm2，碳化温度为600℃）下，罗红霉素的去除率可达75.06%。本研究为利用电fenton工艺进行有机修复提供了创新的概念和技术。
