Abstract
The irreversible adsorption capacity of radioactive cesium in soil of granite origin was assessed via a desorption experiment. The results demonstrated that the cesium desorption only occurred when it reached 0.035% of the cation exchange capacity, despite the presence of the competing ion (K+). The fixation of cesium on frayed edge sites, primarily ascribed to weathered mica and interpretable via the dual-site Langmuir model, may contribute to this irreversible binding. Consequently, the extraction of these minerals from granite-origin soil possesses the potential to diminish the concentration and volume of radioactive soil waste contamination.
