磁性氧化石墨烯的制备及其对pb2+的吸附研究

摘要

Magnetic composite material of graphene oxide/Fe3O4 was prepared under alkaline condition by one-step co-precipitation using ferrous chloride,ferric chloride and graphene oxide as raw.The structure of the as-prepared composite was characterized by IR,TG,XRD and so on.The adsorption and separation experiment for lead ions was carried out by ultraviolet spectrophotometry.The results show that the magnetic graphene oxide composite material was successfully prepared and possessed good adsorption property and magnetic separation effect for lead ions.%采用一步共沉淀法,以FeCl2·4H2O、FeCl3·6H2O和氧化石墨烯为原料,在碱性条件下制备得到氧化石墨烯/四氧化三铁的磁性复合材料,通过红外、热质量和XRD等测试手段对复合材料的结构进行了表征,采用紫外分光光度计法进行了复合材料对pb2+溶液的吸附分离实验.结果表明,制备所得到的磁性氧化石墨烯复合材料对pb2+具有良好的吸附性能和磁性分离效果.
