The discharge of organic pollutants, including pharmaceuticals and dyes, into water systems through waste streams originating from urban, industrial, and various sources is a global challenge. Pharmaceuticals and synthetic dyes rank among the most preva‎lent contaminants in aquatic ecosystems, posing diverse life-threatening issues for both humans and other organisms. Nano composite materials utilizing graphene oxide/ferrite/polymer have been employed to address this concern. In this study, a nanocomposite was synthesized using the aforementioned components, incorporating gum arabic polymer for binding with thiourea. The resulting nanocomposite was assessed for its efficacy in absorbing both colored compounds and pharmaceutical pollutants within water resources. The properties of the synthesized nanocomposite were scrutinized through techniques such as X-ray diffraction spectroscopy, scanning electron microscopy and identification, thermal calorimetry, specific area measurement, vibrating sample magnetometry, and infrared analysis. Simulation techniques were employed to identify the specific pollutants, guiding subsequent experimental procedures. Parameters such as the optimal quantity, pH levels, isotherms, and kinetics were systematically investigated for the absorption of crystal violet dye and gemifloxacin drug. The kinetics of the synthesized nanocomposite were explored using pseudo-first-order and pseudo-second-order velocity equations. The nanocomposite exhibited conformity to the pseudo-second-order kinetic model. Additionally, the isotherm of the nanocomposite was examined, revealing adherence to the Freundlich model.
