Abstract
Nitrogen modified reduced graphene oxide (N-RGO) was prepared by a hydrothermal method. The nitrogen modification enhanced its adsorption and catalysis ability. For an initial bisphenol concentration of 0.385 mmol L(-1), the adsorption capacity of N-RGO was evaluated as 1.56 and 1.43 mmol g(-1) for bisphenol A (BPA) and 1.43 mmol g(-1) for bisphenol F (BPF), respectively, both of which were about 1.75 times that (0.90 and 0.84 mmol g(-1)) on N-free RGO. N-RGO could activate persulfate, producing strong oxidizing sulfate radicals. The apparent degradation rate constant of BPA on N-RGO was 0.71 min(-1), being about 700 times that (0.001 min(-1)) on N-free RGO. In mixtures of various phenols, the degradation rate…
