摘　　要：文章将羧基化柱[5]芳烃和磁性氧化石墨烯通过缩合法制备了阴离子水溶性柱[5]芳烃-磁性氧化石墨烯纳米复合物(MGO@CP5),并将MGO@CP5用于吸附水中碱性品红。凭借柱[5]芳烃提供的主-客体相互作用以及静电相互作用,MGO@CP5对碱性品红表现出良好的吸附性能和较好的去除效率。MGO@CP5对碱性品红的吸附具有优良的pH耐受性和抗离子强度干扰性,还具有易回收和重复利用性高的特性。A carboxylatopillar[5]arene-modified magnetic graphene oxide(MGO@CP5)was successfully prepared and used to remove basic fuchsin from water. Due to the strong supramolecular host-guest interactions and electrostatic interactions provided by carboxylatopillar[5]arene,MGO@CP5 displayed excellent adsorption performance and removal efficiency for basic fuchsin. Additionally,MGO@CP5 exhibited good resistance towards pH changes and inorganic salts interference during adsorption process,and has the properties of easy recyclability and highly reusability.
