Numerical Modeling of Leaching of Aluminophosphate Glass in the Batch Mode in the Presence of Bentonite
A numerical kinetic model of leaching of aluminophosphate glass, an analog of a glass matrix for radioactive waste, in the batch mode in the presence of bentonite, taking into account the sorption processes, was constructed on the basis of the experimental data. The model describes the glass dissolu...

| description | A numerical kinetic model of leaching of aluminophosphate glass, an analog of a glass matrix for radioactive waste, in the batch mode in the presence of bentonite, taking into account the sorption processes, was constructed on the basis of the experimental data. The model describes the glass dissolution kinetics within the framework of the concept of approach to the equilibrium, taking into account shielding of the surface with glass corrosion products. The sorption is described within the framework of the ion exchange model. Modeling was performed using PhreeqC code. |
