This review summarizes the mechanisms for desorbing and extracting cesium (Cs +) from clay minerals and soil. Most techniques use ion exchange with acids, cations, polymers, and surfactants. Some improve desorption of Cs + from clay minerals, while surfactants and polymers expand the interlayer. Mixtures of acids/polymers, acids/surfactants ...

The effect of ball milling process on the properties of the natural local clay including structural changes and adsorption capacity for the removal of Ni(II) ions from aqueous solutions, was investigated. The local clay was ground at varying times from 5 to 20 h with a 10:1 or 20:1 weight ratio of the balls to powder, which produced six different ball milled clays (BMClay1 to BMClay6).
