金刚烷胺/氧化石墨烯复合材料的制备及其吸附性能

以氧化石墨烯和金刚烷为原料，通过水相合成法制备了金刚烷胺功能化氧化石墨烯复合材料A/GO，以FT-IR、XRD和XPS对A/GO进行了结构表征，并考察了A/GO对有机染料的吸附性能。结果表明，与氧化石墨烯相比，A/GO对甲基蓝（AB93）表现出高效吸附性，其吸附动力学和吸附等温模型分别符合拟二级动力学和Langmuir模型，理论最大吸附容量（qm）为1250.0 mg/g。热力学分析表明，A/GO吸附AB93是自发的放热过程。A/GO吸附AB93对盐（NaCl和KCl）表现出良好的耐盐性，而CaCl2能有效地促进A/GO吸附AB93。对于刚果红和AB93等的混合染料体系，A/GO能选择性吸附AB93。

Preparation and adsorption properties of amantadine/graphene oxide composites

Used graphene oxide and adamantane as raw materials, the amantadine functionalized graphene oxide composites (A/GO) were prepared through an aqueous phase synthesis method, and their structures were characterized by FT-IR, XRD and XPS. Compared with graphene oxide, A/GO has more efficient adsorption performance for methyl blue (AB93). The adsorption kinetics and adsorption isotherm model of A/GO adsorption of AB93 accord with pseudo second-order kinetics and Langmuir model. Theoretical maximum adsorption capacity of A/GO (qm) can achieve 1250.0 mg/g. Thermodynamic analysis shows that the adsorption of AB93 by A/GO is a spontaneous exothermic process. A/GO adsorbed AB93 showed good resistance to salts (NaCl and KCl), while CaCl2 could effectively promote A/GO adsorbed AB93. In addition, A/GO can also efficiently and selectively adsorb AB93 from the mixed dyes of congo red and AB93.
