Abstract

The sorption mechanism of 75Se(IV) on Amberlite MB9L is investigated under a wide range of pH, initial concentration, and resin weight to give a proper solution for the decontamination as a result of radioactive selenium. The sorption ability of is found to be high except in highly acidic environment. A monolayer exchange mechanism is confirmed and the reaction rate is found to be controlled by diffusion. The overall equilibrium equation and sorption parameters are estimated. Thus, Amberlite MB9L can be used as barrier to avoid the release of radioactive selenium from the stored nuclear wastes when exposed to groundwater.
