Cation-exchange capacity - Wikipedia
Cation-exchange capacity is measured by displacing all the bound cations with a concentrated solution of another cation, and then measuring either the displaced cations or the amount of added cation that is retained. Barium (Ba 2+) and ammonium (NH 4 +) are frequently used as exchanger cations, although many other methods are available.

Kaolinite - Wikipedia
Kaolinite has a low shrink–swell capacity and a low cation-exchange capacity (1–15 meq/100 g). It is a soft, earthy, usually white, mineral (dioctahedral phyllosilicate clay), produced by the stone weathering of aluminium silicate minerals like feldspar.

Therefore, it suggested that the cationic ACN dyes were successfully loaded on clay minerals due to electrostatic interaction. The inner surface of Hal nanotubes was positively charged while the interlayer of Kal had a lower cation exchange capacity, suggesting that dyes might be adsorbed on the external surface of Kal and Hal [19, 48].

Ion Exchange in Soil: Cation and Anion
The proportion of the cation exchange capacity (C.E.C.) occupied by these bases is called the percentage base saturation. Thus, if the % base saturation is 80 in clay loam soil, 4/5th of the cation exchange capacity (20 meq) is satisfied by bases, the other by hydrogen and aluminium.

The cation exchange capacity of fibers can lead to the increased fecal excretion of minerals and electrolytes (Toma and Curtis, 1986; McDougall et al., 1996). However, the higher cation exchange capacity of fibers may help in binding of heavy metals. Hence, dietary-rich fiber, mineral-depleted diets may cause nutritional problems.
