one-step solvothermal fabrication and characterization of a poly(imide-pyrimidine)-derived magnetic nanocomposite for cu(ii) contamination removal

This study presents the development of a novel poly(imide-pyrimidine)-derived magnetic nanocomposite for cu(ii) removal from aqueous solutions. a one-step solvothermal process was employed to fabricate the nanocomposite, combining a heat-resistant polymer backbone with magnetic iron nanoparticles. the expected functional groups were successfully incorporated into the surface of all composites. the incorporation of fe3o4 was confirmed to be to the polymer matrix, which allowed its effective magnetic separation. the integration of fe3o4 into the polymer matrix was confirmed, facilitating effective magnetic separation. additionally, the performance of the nanocomposite for the removal of cu(ii) was assessed through batch adsorption experiments. optimal conditions were identified using response surface methodology, yielding a ph of 7, an adsorption time of 60 minutes, and an adsorbent dosage of 0.4 g/l. under these conditions, the material demonstrated high efficiency in copper removal, particularly at lower concentrations. at 10 mg/l initial concentration, the nanocomposite achieved 99% removal with an adsorption capacity of 24.75 mg/g. this research contributes to the development of advanced materials for environmental remediation, showcasing the potential of engineered nanocomposites in addressing water pollution challenges.
