Enhanced cesium removal from clay minerals using surfactant-assisted capacitive deionization

This dataset is part of the publication that describes the removal of Cs⁺ from clay minerals using a combined capacitive deionization (CDI) and cationic surfactant approach. It contains the raw data for the reported figures, including Cs⁺ removal efficiency from kaolinite and montmorillonite at different loadings under surfactant-only, CDI-only, and combined treatments, as well as supporting XRD, SEM–EDX, and sequential extraction data used to evaluate structural changes and Cs partitioning.
