dc.description.abstractOn the basis of experimental breakthrough curves of lead ion adsorption on ETS-10 particles in a fixed-bed column, we simulated the breakthrough curves using the two-phase homogeneous diffusion model (TPHDM). Three important model parameters, namely the external mass-transfer coefficient (kf), effective intercrystal diffusivity (De), and axial dispersion coefficient (DL), were optimally found to be 8.33 × 10-5 m / s, 2.57 × 10-10 m2 / s, and 1.93 × 10-10 m2 / s, respectively. A good agreement was observed between the numerical simulation and the experimental results. Sensitivity analysis revealed that the value of De dictates the model performance while the magnitude of kf primarily affects the initial breakthrough point of the breakthrough curves. © 2008 Elsevier Inc.
