摘要：

Thermodynamic parameters derived from experimental results were determined for the potassium-calcium and magnesium-calcium exchange reactions on a kaolinitic soil clay separated from the B horizon of a strongly weathered soil profile. The clay samples were equilibrated at 10 degree and 30 degree C with a mixed solution of KCl and CaCl//2 for the K-Ca system or MgCl//2 and CaCl//2 for the Mg-Ca system.
