Abstract

This study explored the sorption behavior and mechanism of U(VI) on sericite. The surface properties of sericite were investigated, and the effects of several environmental factors on U(VI) sorption to sericite were evaluated. The experimental data were simulated by different isotherm models and kinetic models. Humic acids affects U(VI) sorption obviously while silicate promotes the process in the whole pH range. The sorption–desorption hysteresis suggests an irreversible sorption process. Spectroscopic analyses indicate that the −OH groups have an important effect in the U(VI) sorption.
