Summary Cation exchange studies have been carried out between Mg-saturated bentonite and vermiculite and a number of monovalent electrolytes. According to the distribution and selectivity coefficients the cations are preferred in the order: Li ⪋ Na〈K〈NH4〈Rb〈Cs〈H〈(CH3)4N ⪋ (C2H5)4N for betonite and Li 〈 Na 〈 NH4 〈 K 〈 Rb 〈 Cs 〈 H and (C2H5)4N 〈 (CH3)4N for vermiculite. The selectivity coefficient of H+ is found to be much greater than other inorganic ions. TheΔG-values of the cation exchange reaction have been calculated by an equation ofBarrer. The experimental data were analyzed by the theoretical approach ofPauley too.
