Uranium adsorption experiment was conducted to study the influencing factors and the adsorption mechanisms. The results show that the acidified albite hardly absorbs U(VI) at pH < 4, indicating that it doesn’t affect U(VI) recovery in in-situ leaching process. However, the adsorption percentage of U(VI) quickly increased to 84.9% at pH = 6, then, gradually decreased, with a value always above 40%. Therefore, the acidified albite can prevent U(VI) migration in the post-mining groundwater to a certain extend. The maximum adsorption capacity is 0...
