Abstract
This paper is concerned with the kinetics of uranyl ion adsorption by the amorphous silicon dioxide. The analytical data were approached from following kinetics models: First-order kinetic model, Pseudosecond order kinetic model, Elovich kinetic model, intraparticle model, Bangham model and liquid films diffusion model. The Second-order kinetic model was shown to be the best fit for the description of uranyl adsorption. Keywords: adsorption, kinetics, uranyl ions, silicon dioxide.
