Abstract: The kinetics of sorption from a solution onto an adsorbent has been explored theoretically. The general analytical solution was obtained for two cases. It has been shown that at high initial concentration of solute (sorbate) the general equation converts to a pseudo-first-order model and at lower initial concentration of solute it converts to a pseudo-second-order model. In other words, the sorption process obeys pseudo-first-order kinetics at high initial concentration of solute, while it obeys pseudo-second-order kinetics model at lower initial concentration of solute. The theoretical results (derived equations) show that the observed rate constants of pseudo-first-order and pseudo-second-order models are combinations of adsorption and desorption rate constants and also initial concentration of solute. The obtained theoretical equations are used to correlate experimental data for sorption kinetics of some solutes on various sorbents. The predictions of the theory are in excellent agreement with the experimental data.

Sorption of cadmium on hydrous ferric oxide at high sorbate/sorbent ratios: Equilibrium, kinetics, and modeling

TL;DR: Farley et al. as mentioned in this paper presented a two-site surface complexation model to fit the equilibrium data for cadmium sorption on hydrous ferric oxide and showed that rate expressions based on two site types are necessary and sufficient for high sorbate/sorbent ratios.

Abstract: Equilibrium and kinetics data for cadmium sorption on hydrous ferric oxide are presented for a wide range of sorbate/sorbent ratios. The equilibrium data follow a Langmuir isotherm at low Cd2+ concentrations (<10−6 M), a Freundlich isotherm at low to moderate concentrations (10−6–10−3 M), and exhibit a maximum sorption density at the highest concentrations. A two-site surface complexation model is needed to fit the equilibrium data. To describe the expected transition from adsorption to precipitations as Cd(OH)2(s) saturates, the surface precipitation model (Farley, K. J., Dzombak, D. A., and Morel, F. M. M., J. Colloid Interface Sci. 106, 226, 1985) can be incorporated in the two-site complexation model without addition of fitting parameters. The kinetics of cadmium sorption slow considerably as the sorbate/sorbent ratio is increased, and these results are consistent with the equilibrium data in that rate expressions based on two site types are necessary to fit the kinetics data corresponding to high sorbate/sorbent ratios.
