The sulfamethazine drug interaction with carbon nanotubes was investigated with the aim of improving the adsorption capacity of the adsorptive materials. Experiments were performed to clarify how the molecular environment affects the adsorption process. Single-walled carbon nanotubes have a higher removal efficiency of sulfamethazine than pristine or functionalized multi-walled carbon nanotubes. Although the presence of cyclodextrin molecules improves the solubility of sulfamethazine, it reduces the adsorption capacity of the carbon nanotube towards the sulfamethazine drug and, therefore, inhibits the removal of these antibiotic pollutants from waters by carbon nanotubes.
研究了磺胺甲噁唑与碳纳米管的相互作用，旨在提高吸附材料的吸附容量。实验旨在阐明分子环境如何影响吸附过程。与原始或功能化多壁碳纳米管相比，单壁碳纳米管对磺胺甲噁唑的去除效率更高。尽管环糊精分子的存在提高了磺胺甲噁唑的溶解度，但它降低了碳纳米管对磺胺甲噁唑药物的吸附能力，从而抑制了碳纳米管从水中去除这些抗生素污染物。
