ResumoAn experimental study was made of several cation-exchange reactions on a Yolo loam soil by means of a leaching procedure. Adsorption isotherms for the K-Na, K-Mg, K-Ca, and Mg-Ca ion pairs were obtained. An application of thermodynamic equations was used to find the equilibrium constants and free-energy changes for the reactions. Activity coefficients of the adsorbed ions were also calculated. A comparison of various selectivity coefficients was included.
