摘要
我们利用从废旧水滤芯(UWFC)中提取的活性炭(AC),开发了一种废物资源化去除水中染料的方法。在400°C下轻度再活化1 h生成AC-UWFC,随后转化为磁性活性炭(MAC-UWFC),用于高效吸附亚甲基蓝(MB)。表征证实了具有高稳定性的介孔结构(BET: 404.78 m2−1)。在pH为8时,使用0.2 g MAC-UWFC超过1小时,吸附效果最佳。吸附遵循Langmuir等温线(227.27 mg−1)和准二级动力学。经过8个循环后,MAC-UWFC的处理效率仍保持在92.32%,证明了其处理废水的有效性。
Eco-friendly synthesis of magnetic activated carbon from used water filter cartridges for efficient methylene blue adsorption
Using activated carbon (AC) derived from used water filter cartridges (UWFC), we developed a waste-to-resource method to remove dyes from water. Mild reactivation at 400 for 1 h produced AC-UWFC, which was subsequently transformed into magnetic activated carbon (MAC-UWFC) for efficient adsorption of methylene blue (MB). Characterization confirmed a mesoporous structure (BET: 404.78 ) with high stability. Optimal adsorption occurred at a pH of 8, using 0.2 g of MAC-UWFC over 1 h. Adsorption followed the Langmuir isotherm (227.27 ) and pseudo-second-order kinetics. MAC-UWFC maintained an efficiency of 92.32 % after eight cycles, demonstrating its effectiveness in wastewater treatment.
