摘要

Graphene oxide(GO)has attracted a significant interest in the field of sorption in recent years because of its high specific surface area,excellent chemical stability and mechanical strength.GO has been used as an effective sorbent for heavy metal ions[1]and organiccontaminant[2]removal from water solutions.All of the results suggested that the oxygen containing functional groups(carboxyl,epoxy and hydroxyl groups)on the surface of GO played an important role in the containment elimination.Hence,if more oxygen containing functional groups can be introduced into the GO structure,its sorption capacity for hazardous materials will be certainly increased.Moreover,GO with high oxygen content will warrant its good solubility and used as a good candidate in other fields.
