Migration of radionuclides in porous rock in the presence of colloids: effects of kinetic interactions

摘要

This work investigates the colloids-facilitated migration of radionuclides with radioactive decay in porous media. The sorption processes for radionuclides with both the solid matrix and colloids are treated as equilibrium or nonequilibium. An analytical solution is obtained from a simplified linear equilibirum interaction mechanism. In addition, the adsorption processes for radio- nuclides with colloids and porous rock can be assumed as nonequilibrium and modeled by the linear kinetic adsorption.
