Illite, a kind of clay mineral, was taken as an adsorbent in an experiment for low-concentration rare earth ions in rare earth leaching solution to explore effects of initial concentration of Y3+, adsorption temperature, pH value of solution, ion concentration, and adsorption time on the adsorption behavior of illite. Then, based on the constructed isotherm model for adsorption of yttrium ions by illite and its reaction kinetic model, the mechanism for the adsorption of yttrium ion by illite was analyzed. Results show that illite has an excellent adsorption performance for Y3+. With an increased initial concentration, higher temperature, prolonged time, and higher pH value of solution, the adsorption capacity of Y3+ for illite increases. It is found that the existence of Na+, Mg2+ and Al3+ can inhibit the adsorption of Y3+ by illite in the following descending order of importance: Al3+>Mg2+>Na+. The adsorption reaction follows Langnuir isotherm model and pseudo-second-order reaction kinetic model. Ion exchange reaction takes place during the adsorption process, thus this adsorption process belongs to chemical adsorption, with adsorption rate controlled by chemical reaction.
