摘　　要：以废弃物甘蔗渣为原材料采用直接炭化法合成三维类石墨烯纳米材料,研究了其对环丙沙星(CIP)模拟废水的吸附性能。通过单因素实验探究了吸附剂投加量、溶液pH、初始浓度、反应时间对甘蔗渣生物质类石墨烯去除水溶液中环丙沙星抗生素的影响。结果表明,生物质类石墨烯对环丙沙星具有良好的吸附能力,可以高效地去除抗生素。同时类石墨烯对环丙沙星的吸附符合准一级动力学模型和Langmuir吸附等温模型,并且最大吸附量可以达到606.53 mg/g。In this study, three-dimensional graphene-like nanomaterials were synthesized from bagasse by direct carbonization, and their adsorption properties for ciprofloxacin(CIP) simulated wastewater were investigated. The effects of the adsorbent dosage, pH, initial concentration, and reaction time on the removal of CIP were studied by single-factor experiments. The results showed that prepared graphene had excellent adsorption ability of CIP for efficient removal of antibiotics. At the same time, the adsorption of CIP by prepared graphene was following the Pseudo-first-order kinetics model and Langmuir adsorption isotherm model, and the maximum adsorption capacity could reach 606.53 mg/g.
