Progress of graphene materials on adsorption and purification
Graphene was a sheet layer high specific surface area of carbon materials,the theory of specific surface area was up to 2 630 m2/g,has high adsorption capacity,good chemical stability and mechanical properties, etc.The development and application of graphene has become one of the current hot research topics.This review presents the current status of grapheme and its composites in adsorption of heavy metal ions,organic pollutants and poisonous gas.In the end ,the problems in the application of grapheme and its composites in adsorption are pointed out ,then the roles of grapheme and its composites in adsorption are summarized and prospects for fu-ture research in this field are proposed.
