A competitive adsorption model was used to describe the sorption equilibrium of germanic acid and its dissociation products to glucose sites and to amine groups. A transport-dispersive model with a solid film linear driving force model was employed for the dynamic modeling. Authentic and simulated feed solutions were used to study the effect of competing metals. The feed solutions contained 63–490 mg/L Ge and metal sulfates so that ionic strengths were between 0.58 and 5.82 mol/L. The constructed simulation model predicted the equilibrium isotherms and the breakthrough curves of germanium well.
