Film-pore diffusion model for the fixed-bed sorption of copper and cadmium ions onto bone char

摘要

the sorption of copper and cadmium ions onto bone char in single component systems has been studied using fixed-bed column adsorbers. The effects of solution flowrate, initial metal ion concentration and bone char particle size have been studied. A film-pore diffusion model has been develop to predict the fixed-bed breakthrough curves for the two metal ions.
