Heavy toxic metal ion exchange kinetics: Validation of ion exchange process on composite cation exchanger nylon 6,6 Zr(IV) phosphate

Nernst–Planck equation was applied to study the heavy metal ion exchange kinetics over the surface of nylon 6,6 Zr(IV) phosphate at various temperatures under particle diffusion controlled phenomena. Various useful ion exchange kinetic parameters such as self-diffusion coefficient (Do), energy of activation (Ea), and entropy of activation (ΔS*) were evaluated to validate the ion exchange process for practical applicability of this composite cation exchanger in remediation processes of the environment. This study is also supported for the good selectivity of Cu(II) to validate the practical application of this cation exchanger in environmental analysis.
