摘　　要：通过水热还原-冷冻干燥法制备了氧化石墨气凝胶材料,研究了氧化石墨气凝胶处理铜离子废水的可行性,主要探索了氧化石墨气凝胶在不同铜离子浓度、不同溶液pH值、不同反应时间和不同反应温度下对铜离子的吸附性能。通过条件优化,最终得到了氧化石墨气凝胶处理铜离子废水的最佳吸附条件。In this paper,graphite oxide aerogel materials were prepared by the hydrothermal reduction-freeze-drying method,and the feasibility of graphite oxide aerogel in the treatment of copper ion wastewater was studied.Then,the effect of copper ion concentrations,solution pH value,reaction time and different reaction temperature on the adsorption performance was examined.Through optimization of conditions,the best adsorption conditions for the treatment of copper ion wastewater by graphite oxide aerogel were finally obtained.
