Abstract Here, a new hierarchical porous carbon was first prepared from sodium lignosulphonate (SLS), an industrial by-product, via a confined carbonization and alkali activation methods using graphene oxide (GO) as template, and was used for ciprofloxacin (CIP) removal. The addition of GO nanosheets remarkably affected the morphology and pore structure. GLHPC-1, obtained at GO/SLS weight ratio of 1:100, possess a largest specific surface area of 3223 m2 g−1 and pore volume of 2.275 cm3 g−1, and thus exhibited an ultrahigh adsorption of 980.4 mg g−1 at 318 K and fast adsorption rate, as well as a good recycle ability in practice.

氧化石墨烯模板限制的木质素衍生多级多孔碳的制备，用于超高效和快速去除环丙沙星

摘要 在此，首次以工业副产品木质素磺酸钠 (SLS) 为原料，以氧化石墨烯 (GO) 为模板，通过受限碳化和碱活化方法制备了一种新型分级多孔碳，并将其用于环丙沙星 (CIP) 的去除。 . GO纳米片的添加显着影响了形态和孔结构。GLHPC-1 以 GO/SLS 重量比为 1:100 获得，最大比表面积为 3223 m2 g-1，孔体积为 2.275 cm3 g-1，因此具有 980.4 mg g-1 的超高吸附量在 318 K 和快速的吸附速率，以及在实践中良好的回收能力。
