Abstract

This paper derived a columnar model to study the kinetics of Cd(II) adsorption on strong acid cationic exchange fiber (SACEF). Mass transfer rate model ion exchange under liquid film control was derived from dynamic adsorption data. The solution of this model was F((t) = 1 - e^-Rt; R = 2D(Rć+ Vc)/(r₀ćV) in solution with finite volume, while R = 2Dc/(r₀ć) in infinite volume. An overall mass transfer coefficient model and its equations were set up under different aqueous concentrations. The simulated results of liquid film control basically correspond to the experimental data, which means it can be used in engineering applications. The value of liquid film diffusive coefficient D was between 10^-14 and 10^-12 m²·min^-1, and the range of was 10^-6 to 10^-8 m.
