Abstract : Organic radical cations will dimerize when adsorbed to the surface of montmorillonite in colloidal solution. This dimerization is primarily the result of a concentration effect and the ability of organic probes to colonize or sequester on the clay particle surface or within its layers. The adsorption of organic cations to the clay surface is primarily a cation exchange process. The rate constant for cation exchange is 3.25 x 10 to the 6th power L/equivalents sec.
