Polymers, Removal, Cadmium IonsAbstract
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
