氧化石墨烯与纳米氧化铁复合物的制备及性能研究

The Preparation and Properties Graphene Oxide Sheets/Nanosized Yellow Iron Oxide Composites

文章用Hummers法制备氧化石墨,以绿矾为原料、采用氯酸钠氧化制备纳米氧化铁,采用超声共混,搅拌,烘干制的复合物,通过FT-IR/TG/TEM等进行表征,结果表明,氧化石墨完全剥落,氧化铁在内分散很好,两者界面相容很好。复合材料吸附性好,有很好吸附砷的功能。

Graphene Oxide（GO） was prepared in Hummers.Nanosized yellow iron oxide was produced by the oxidation method of sodium chlorate using the ferrous sulfate Composites was prepared under the ultrasonic stirring oven dry.FT-IR/TG/TEM／ Were employed to characterize these composites membranes.The results suggest that GO was exfoliated totally and yellow iron oxide distributes well in the matrix,and the interface between GO and yellow iron oxide of the composites were quite compatibility these composites were evaluated as absorbents for arsenate removal from contaminated drinking water.
