Numerical modeling examines leaching dynamics of borosilicate glass and bentonite interactions, indicating long-term processes.
The paper presents a numerical kinetic model of borosilicate glass matrix leaching in the presence of bentonite developed with an account taken of leaching kinetics, surface inhibition by secondary glass matrix transformation products, as well as the kinetics of bentonite phase transformation and sorption processes. The model was developed based on an experimental study. The chemical processes were modeled using the PhreeqC calculation code. The study notes that leaching continues non-stop all through the entire modeling period (1,400 years).
