The depletion of pharmaceutical and personal care products into water sources has raised a growing concern because of their deteriorating effects on human health and the environment. The removal of these pollutants before disposing of them to nature seems to be necessary. In this regard, Fe3O4@PAA@UiO-66-NH2 magnetic core-shell nanocomposite was developed and used for the selective adsorption of the Quercetin (QCT) anti-cancer drug. Several characterizations like FTIR, XRD, BET, FESEM, and TEM techniques were employed to ensure nanoparticles' quality. The effect of determining parameters like exposure duration, initial QCT concentration, temperature, and adsorbent dose on the nanoparticle performance was enlightened. The selective adsorption of QCT in different mixtures containing three widely used anti-cancer drugs, I,e QCT, CUR, and MTX, has been investigated. The pseudo-second-order kinetic and Langmuir isothermal models were too fitted to the adsorption results. The maximum adsorption capacity of 264.11 mg/g at 20°C was obtained for QCT. The magnetic nanocomposite equilibrium adsorption capacity for QCT was measured to be 75.18 mg/g, 33% and 48% more than that of MTX and CUR, showing the selective adsorption of QCT. Excellent solvent stability, fast regeneration, strong adsorption selectivity, and high adsorption capability promise Fe3O4@PAA@UiO-66-NH2 nanocomposite as effective adsorbents for QCT adsorption.
