摘要：

In this study, an attempt is made to investigate the behavior of the ion exchange involving hard barium and lanthanum cations. For this purpose, from calorimetric titration of a suspension of the exchanger in water with the select cations, the thermochemical data of the reactions are explored. As a result, the influence of the charge of the cations on ion exchange is clarified.
