The program ''Countercurrent'' is developed for the simulation of a co
ntinuous ion-exchange extraction of strontium from strongly mineralize
d NaCl and CaCl2 solutions using a KB-4 carboxylic cation-exchanger in
the countercurrent columns. The program allows one to calculate the c
onditions of Ca and Sr separation depending on the mode of operation a
t the sorption and regeneration stages, the residual Sr content on the
overloaded sorbent, and the Sr separation on incompletely regenerated
KB-4. It also makes it possible to find the optimal separation condit
ions. The program ''Countercurrent'' can be also used to simulate othe
r ion-exchange processes.
