摘要：
This study investigated the adsorption of Eu(III) from simulated Beishan groundwater onto Gaomiaozi bentontie. The effects of shaking time, temperature, concentration of the adsorbent, pH value and concentration of Eu(III) were analyzed. Results showed that the adsorption could reach the equilibrium at 45 min and the maximum adsorption capacity can get to 4.52 mg/g. The optimum pH was observed above 8.5 at temperature 298 K; the adsorption capability increased with the pH value increasing from 2 to 12, which are expected to occur in the near field of Chinese repository. The adsorption process could be described with the Freundlich isotherm.
