    Modeling Adsorption-Desorption Processes of Cd on Montmorillonite

    Adsorption-desorption of Cd to Ca montmorillonite (SAz-1) was studied at concentrations ranging from 44.5 to 266.8 μM. An adsorption model was employed in the analysis of the data. The procedure consists of solvi...

    Use of Methylene Blue and Crystal Violet for Determination of Exchangeable Cations in Montmorillonite

    A procedure for the determination of cation exchange capacity (CEC) and the amounts of exchangeable cations adsorbed to montmorillonite is proposed. The method consists of a single incubation of the clay in a ...

    Model for Competitive Adsorption of Organic Cations on Clays

    The adsorption on montmorillonite of two monovalent organic cations, methylene blue (MB) and thioflavin T (TFT), was studied in four different situations: (1) separate adsorption of MB or TFT; (2) competitive ...
