Gharenaz bentonite contains montmorillonite as the major mineral constituent and Ca as the major exchangeable cation. In the present study, the structural changes occurred in the course of acid activation of this bentonite was investigated by chemical analysis using ICP-AES and phase analysis using XRD methods. Chemical analysis showed that most of the exchangeable cations i.e. K+, Na+ and Ca2...

Accurate modeling of multicomponent sorption and transport of major cations in subsurface porous media is a prerequisite for predicting complex environmental processes, such as the movement of trace metals in soils and aquifers. In this study, various cation exchange models were compared in their ability to predict ternary Ca–Mg–Na transport in an acidic soil from binary Ca, Mg, and Na adsorpti...
