通过水热合成法，用植酸（phytic acid）与氧化石墨烯（graphene oxide）反应制备了一种三维结构的石墨烯材料（PA‐GO ）。利用扫描电子显微镜（SEM ）、傅里叶‐红外光谱仪（IR）、X射线晶体衍射仪（XRD）对PA‐GO的形貌和结构进行表征，结果表明，该材料具有膨松的多孔状结构，有利于对有机物的吸附和回收。将其用于对亚甲基蓝的吸附，研究了吸附时间、溶液初始浓度和温度对吸附效果的影响。研究表明，吸附在45．h达到平衡，最大吸附量为927．mg／g ，且升高温度有利于 PA‐GO 对亚甲基蓝的吸附。Langmuir等温模型能够较好地描述PA‐GO对亚甲基蓝的吸附。

A new three‐dimensional structure of graphene materials (PA‐GO) was prepared via the reaction of phytic acid with graphene oxide via hydrothermal synthesis method .The morphology and structure of PA‐GO was then characterized by SEM ,FT‐IR ,XRD and it demonstrates that the material has a sponge‐alike struc‐ture .Then the material was used as the adsorbent for methylene blue (MB) ,and the effects of adsorption time , initial concentration and temperature were investigated ,respectively .The results indicated that the adsorption process was completed within 4 .5 h ,the maximum sorption capacity of PA‐GO for MB was evaluated to be 92 7. mg/g ,and the sorption efficiency of MB on the PA‐GO increases with the rise of temperature ,the adsorp‐tion isotherms were according with the Langmuir model .
