摘　　要：海洋为人们提供丰富资源的同时也受到众多的污染,其中以石油污染为代表。采用维他命C简易还原方法将氧化石墨烯与棉纤维素原位自组装形成三维网状结构复合材料,并使用仪器分析方法进行表征。通过动力学实验、再生实验、模拟海水平衡吸附实验研究石墨烯纤维素复合材料对海水溢油的处理效果。采用Langmuir等温吸附模拟结果显示复合材料对煤油的最大吸附量能达到66.32g/g,而且具有良好的结构稳定性。该石墨烯纤维素复合材料还对煤油、丙三醇、乙二醇和氯仿等多种有机溶剂也展现了良好的吸附性能,复合材料较大的吸附容量归因于材料多孔疏松结构和疏水性的表面结构特性。研究结果将为海水溢油的治理提供有前景的吸附材料和研究基础。The ocean provides people with abundant resources and is also subject to numerous pollutions,including oil pollution.The three-dimensional network structure composites were formed by in-situ self-assembly of graphene oxide and cotton cellulose by the simple reduction method of vitamin C,and characterized by instrumental analysis.The effects of graphene cellulose composites on seawater spills were studied by kinetic experiments,regeneration experiments,and simulated seawater equilibrium adsorption experiments.The results of Langmuir isothermal adsorption simulation show that the maximum adsorption capacity of the composite material to kerosene can reach 66.32g/g,and it has good structural stability.The graphene cellulose composite material also exhibits good adsorption performance for various organic solvents such as kerosene,glycerol,ethylene glycol and chloroform,and the composite material is large.The adsorption capacity is attributed to the porous structure of the material and the hydrophobic surface structure characteristics.The research results will provide promising adsorbent materials and research basis for the treatment of seawater spills.
