  Abstract

The current study was presented a plain, and highly sensitive to remove Pd (II) from wastewater. A modified magnetic multiwall carbon nanotubes with chitosan (Methionine-Chi/MWCNTs-COOH/Fe₃O₄) was created. Through coordination and chelation with the –NH2, –COOH, and –S groups of methionine/chitosan, it achieved 170.5mg g⁻¹ capacity via chemisorption (pseudo-second-order kinetics) using CCD optimization (pH 6.0, 48 mg adsorbent, 15 min contact time, 11 mL eluent). Pd (II) can be effectively removed from actual industrial effluents using this spontaneous and exothermic process. The results indicated that the Langmuir model offered a superior fit for the isotherm data when compared to models of the Freundlich and Temkin. Additionally, the kinetic data showed excellent agreement with the model of pseudo-second-order adsorption. Both physical and chemical adsorption processes were involved, as shown by the negative ΔH values. Overall, the results indicate that Methionine-Chi/MWCNTs-COOH/Fe₃O₄ exhibits strong potential as an adsorbent material for selective Pd (II) removal from industrial effluents.
