In recent decades, lack of control over the entry of various pollutants in various chemical units, especially pharmaceuticals and hospital effluents into the environment has caused destructive and irreversible effects on human health and organisms, as well as the environment and the elimination of these pollutants. It has been raised as an important environmental problem. In this project, a graphene oxide / gum arabic oxide-cerium oxide (GA/GO-CeO2) nanocomposite has been prepared for the first time with a new method to remove the drug contaminant sumatriptan succinate (SS) from aqueous medium. The prepared nanocomposite has been characterized by various analyzes such as BET, EDX map, EDS, FT-IR, TGA, XRD, FE-SEM. Based on FE-SEM images, the average size of nanoparticles deposited on the graphene oxide-gum arabic substrate is estimated in the range of 31-37 nm. Adsorption tests were performed to remove contaminants from the aqueous medium prepared by nanosorbents, and the effect of various parameters such as: pH effect, effect of initial concentration of SS, effect of adsorbent consumption, contact time, isothermal adsorption equilibrium, adsorption kinetics, reusability The adsorbent was examined. Finally, the adsorption analysis results show that the synthesized nanocomposite can be used as an effective nanosorbent to remove somatriptan succinate contaminant from the effluent. After six consecutive cycles of nanocomposite use, well maintain 91% of the initial cycle capacity.
