Abstract The mechanism of highly efficient adsorption of endocrine disruptor bisphenol F (BPF) by reduced graphene oxide (RGO) was investigated in this study. Compared with similar carbonaceous adsorbents (such as GP and GO), RGO exhibit great potential as an efficient adsorbent for removing BPF from waste water. The adsorption isotherm of BPF on the surface of RGO can be well fitted by Freundlich model, which indicated the occurrence of multilayer adsorption of BPF on RGO surface. The results of thermodynamic studies showed that the adsorption of BPF on RGO surface was a spontaneous endothermic process. The adsorption capacity of RGO to BPF increased slowly with the increase of solution pH value from 2.0 to 11.0. After pH exceeded the pKa1 of BPF, there was a rapid raise in the adsorption capacity and interaction affinity until the maximum was achieved. Once the secondary dissociation of BPF occurred, the adsorption capacity and affinity of RGO decreased dramatically, due to the strong electrostatic repulsion. The primary mechanism of highly efficient adsorption of BPF by RGO included π-π interaction, hydrophobic interaction and charge-assisted hydrogen bonding. The different pH value of the solution could lead to significant difference in adsorption capacity of RGO to BPF. This study provided a theoretical basis for the new graphene-based adsorbents used for removing dissociable endocrine disruptors in contaminated water.
