摘要

Molecularly imprinted polymers (MIPs) are specialized cross-linked polymer networks designed

to show strong affinity for specific target molecules, ions, or metallic species. They can also show

remarkable selectivity for structurally related compounds. The creation of a cadmium(II)

ion-imprinted polymer intended for the selective extraction of cadmium ions from aqueous

matrices is described in this work. 4-vinyl pyridine was used as the functional monomer

component in the bulk polymerization process used in the polymer synthesis. Thermogravimetric

analysis (TGA), scanning electron microscopy (SEM), and CHNS elemental analysis were used to

achieve thorough characterization. Equilibrium studies were used to verify the adsorption

properties. The adsorption mechanism is exothermic and follows pseudo-first-order kinetics,

according to kinetic and thermodynamic analyses. When tested in binary ion mixtures, the

synthesized polymer showed exceptional selectivity for Cd(II) ions. Additionally, throughout

several adsorption-desorption cycles, the material demonstrated outstanding regeneration

capability
