摘要
资源循环利用和可再生清洁能源已成为解决世界环境污染和能源短缺问题的必然选择。以废电路板中的非金属组分为碳源,通过活化-磁化两步法制备磁性多孔炭材料,研究了孔隙结构和纳米零价铁对Cr(Ⅵ)吸附行为的影响。室温时,所制备的材料能将100mg/L的Cr(Ⅵ)在120min快速降解,去除率为98.6%。该研究不仅为废电路板的循环利用提供一条新的路径,而且为污水中的重金属吸附提供一种替代材料。
Renewable clean energy and resources recycling have become inevitable choices to solve worldwide energy shortages and environmental pollution problems.It has become a great challenge to recycle waste circuit boards for cleaner production in the industry,while creating value. Magnetic porous carbon materials are prepared by activationmagnetization route using non-metallic components in waste printed circuit boards as carbon sources.The effects of pore structure and nano-scale zero valent iron on the adsorption behavior of the materials to Cr(Ⅵ) are studied. At room temperature,PB800-3-0. 5 ZVI can rapidly degrade 100 mg/L Cr(Ⅵ) in 120 min with a removal rate of 98. 6%. This work not only provides a new way for recycling waste printed circuit board,but also provides an alternative material for heavy metal adsorption in sewage.
