Assessment of the adsorption capacity tetracycline hydrochloride antibiotic in wastewater of graphene oxide materials

In this study, Graphene oxide (GO) was synthesized for the treatment of antibiotic residues in the aquatic environment. The characteristics of GO material were analyzed by the XRD, and SEM methods. The GO material was used for the adsorption of tetracycline hydrochloride (TCH) in an aqueous environment. The adsorption equilibration time is 30 min. The factors that affect the adsorption process were investigated including the initial TCH concentration (10-40 mg/L), the GO content (0,1-0,5 g/L), and the pH solution (1-9). The adsorption process of TCH on GO material is consistent with the Freundlich isotherm model. The TCH adsorption process of GO material is exothermic.
