文摘
- •
Graphene oxide (GO) covalently bonded to the spherical silica.
- •
Very stable sorbent for SPE of metal ions.
- •
Excellent contact with solution due to the softness and flexibility of GO nanosheets.
- •
Several adsorption–elution cycles without any loss of adsorptive properties.
- •
High adsorption capacity due to the wrinkled structure of GO nanosheets.
