- Аннотация: The laboratory study of adsorbing ability (N) of different types of sand-gel material (SGM) of undisturbed and remolded structure (with and without drying) in relation to cadmium was conducted in dynamic mode. The breakthrough curves were obtained and adsorbing abilities were calculated for different types of SGM, the comparative assessment of them was made. The contributions of poorly soluble hydroxide precipitation and adsorption itself to the total immobilization of cadmium were avaluated for each type of SGM. The effect of initial concentration of cadmium in solution and filtration velocity on adsorbing capacity was investigated. The results of study showed the perspectivity of SGM using as geochemical barrier in relation to cadmium.
