Abstract
This study focuses on the synthesis of a biocompatible magnetic nanosorbent, modified with β-cyclodextrin (β-CD), using wheat bran (WB) for the adsorption of the drug S-citalopram (S-CIT). Various characterization techniques, including FTIR, SEM, XRD, and VSM, confirmed the successful creation of the wheat bran/Fe3O4/β-cyclodextrin (WB/Fe3O4/β-CD) nanoadsorbent and its effective interaction with S-CIT. Optimization of parameters such as pH and temperature led to an impressive adsorption efficiency of up to 94%, with a maximum adsorption capacity of 91.74 mg/g under optimal conditions. A calibration curve was established for S-CIT concentrations ranging from 0.2 to 50 μM, yielding a detection limit of 0.050 μM. Thermodynamic and kinetic studies indicated that the adsorption process is exothermic and follows the characteristics of chemisorption. Additionally, it adhered to the Langmuir isotherm model and the pseudo-second-order kinetic model.
