Effect of the reduction degree of graphene oxide on the adsorption of Bisphenol A

- Qmax were 17.27 mg/g, 80.81 mg/g and 94.06 mg/g for GO, RGO and Gr, respectively.
- Desorption of BPA could be totally achieved with diethyl ether-methanol 9:1 (v/v).
- Oxygen-containing surface functional groups had a negative effect on adsorption.
- Main adsorption mechanism is due to π-π interactions.
