Characterization of clays by organic compounds
TL;DR: In this article, four clay-organic reactions are used: staining tests and dye adsorption, glycerol and glycol adaption, intercalation, and alkylammonium ion exchange.

Clay mineral-organic interactions
TL;DR: In this article, the interaction of 2:1 clay minerals with neutral organic molecules such as alcohols, fatty acids, amino acids, aromatic compounds, macrocyclic compounds, and nuclein bases is discussed.

Determination of the cation exchange capacity and the surface area of bentonite, illite and kaolinite by methylene blue adsorption
Günter Kahr,Fritz T. Madsen +1 more
TL;DR: In this article, the surface area of bentonites can only be calculated with methylene blue adsorption when the montmorillonite surface area per charge corresponds with the area of the methylene-blue cation of 130 A 2, i.e. the interlayer charge of the Montmorillonites must amount to 0.28-0.33 charges per half unit cell.

Chapter 7.3 Clay Mineral Organic Interactions
TL;DR: In this article, the authors review the interaction of 2:1 clay minerals with different types of polymers including polypeptides and proteins, and show that they can react with various types of organic compounds in particular ways.

In Situ Study of CO2 and H2O Partitioning between Na–Montmorillonite and Variably Wet Supercritical Carbon Dioxide

TL;DR: In situ X-ray diffraction and in situ infrared spectroscopy were used to investigate the swelling/shrinkage and H2O/CO2 sorption of montmorillonite, and the results may aid predictions of shale caprock integrity in large-scale GCS as well as methane transmissivity in enhanced gas recovery operations.

TL;DR: Values obtained for montmorillonite agree closely with theoretical values based on liquid glycerol density, while vermiculite retains a mono-interlayer of somewhat less than liquid glycersol density.
