▎ 摘  要

Two carbonaceous materials were prepared and characterized for their effectiveness in eliminating bisphenol A (BPA) and carbamazepine (CBZ) from aqueous solution. The adsorption of these pollutants was investigated because these compounds are unregulated in water legislation and their prevalence and toxicity require special attention related to their removal. There is a global concern linked to indirect ingestion of endocrine disrupting compounds (EDCs) and pharmaceuticals due to their deleterious effects on humans and animal health. In order to determine the optimum adsorption parameters, the influence of the contact time and of the initial concentration of pollutant were investigated. According to the Langmuir model, the maximum adsorption capacity (q(max)) of partially reduced graphene oxide (PRGrO) for BPA and CBZ (346.07 mg/g respectively 55.13 mg/g) was higher than q(max) of graphene oxide (GO) (92.40 mg/g, respectively 32.35 mg/g). Considering these results, we suggest that partially reduced graphene oxide is a promising and effective adsorbent for the removal of bisphenol A and carbamazepine from aqueous solutions. To our knowledge, there are no other studies related to the adsorption of these pollutants on partially reduced graphene oxide.
