Abstract

Hazardous substances originating from aromatic compounds pose seriously harmful effects on aquatic animals and the environment, which has received the attention for the treatment. This work used Multi-Walled Carbon Nano-Tubes (MWCNTs) modified with vanadium-pentoxide V₂O₅ nanoparticles and 2 wt% of different nanocomposite mixtures to remove methylene blue from water. The process for adsorption has been carried out using different metal oxides modified MWCNTs and V₂O₅/MWCNTs resulting in the highest adsorption capacity, 50.93 mg/g for methylene blue). The V₂O₅:CeO₂ nanocomposites modified MWCNTs exhibited the highest removal efficiency with 63.77 %, superior to previous studies.

改性多壁碳纳米管纳米复合材料去除水中阳离子染料

芳香族化合物产生的有害物质对水生动物和环境造成了严重的危害，已引起人们的重视。本研究使用五氧化二钒V2O5纳米粒子和2 wt%不同纳米复合材料混合物修饰的多壁碳纳米管(MWCNTs)去除水中的亚甲基蓝。不同金属氧化物改性MWCNTs和V2O5/MWCNTs对亚甲基蓝的吸附量最高，达到50.93 mg/g。V2O5:CeO2纳米复合材料改性MWCNTs的去除率最高，达到63.77%，优于以往的研究。
