The rate of K uptake by the hydrogen form of Amberlite IR‐120 from Fithian illite was studied. Resin‐illite ratio, time in contact of illite with the resin, temperature, and repeated treatment effect on the release of K were investigated. The amount of released K increased as the resin‐illite ratio, time in contact, and temperature increased. It seems probable that amberlite IR‐120 attacks mainly the surface parallel to the c‐axis of illite crystals. Thus, even after a long treatment of illite with the hydrogen form of amberlite, illite keeps its cation‐exchange capacity value, crystal structure, and almost all of its K content. X‐ray graphs of the resin‐treated illite samples after their Mg saturation and ethylene glycol solvation do not present any clear evidence of alteration of illite to expanding lattice type clay minerals.
