As a kind of three-dimensional graphene architecture material with superhydrophobic, low density, high specific surface area and porosity, graphene aerogel (GA) can be used to immobilize extractant to constitute the solvent impregnated adsorbent. In this paper, the N,N,N',N'-tetraoctyldiglycolamide impregnated graphene aerogel ( GA-TODGA) was prepared to remove the thorium from aqueous solution. It is found that the adsorption of thorium on GA-TODGA is strongly dependent on the concentration of TODGA in GA and HNO in aqueous solution. Compared with other solvent impregnated adsorbents, the adsorption capacity of GA-TODGA is much higher due to the high immobilization capacity of GA for TODGA. Furthermore, the GA-TODGA also possesses excellent stability and reusability, ensuring the application potential of using GA-TODGA in large scale.
作为一种具有超疏水、低密度、高比表面积和孔隙率的三维石墨烯结构材料，石墨烯气凝胶（GA）可用于固定萃取剂以构成溶剂浸渍吸附剂。本文制备了 N，N，N'，N'-四辛基二甘酰胺浸渍的石墨烯气凝胶（GA-TODGA），以从水溶液中去除钍。结果表明，GA-TODGA 对钍的吸附强烈依赖于 GA 中 TODGA 的浓度和水溶液中的 HNO3。与其他溶剂浸渍吸附剂相比，GA-TODGA 的吸附容量要高得多，这是由于 GA 对 TODGA 的高固定化能力。此外，GA-TODGA 还具有优异的稳定性和可重复使用性，这确保了 GA-TODGA 在大规模应用中的潜力。
