Abstract
The equilibrium exchange of alkali metal ions (Li+, Na+, K+ and Cs+)/H + system has been studied in MCl-HCl media at 25, 40 and 60 degrees C. The exchange isotherms have been measured for both forward and revers e reactions, at a solution ionic strength of 0.1, by the batch techniq ue. On the basis of the exchange isotherms, thermodynamic parameters h ave been calculated and some predictions made for the exchange process taking place in the materials. The selectivity sequence shows that K < Na+ < Li+ < Cs+.
