The focus is on analytical resolution of the mass‐balance relation in the case of a binary ion‐exchange system containing chloride and hydrocarbonate anions involved in a two‐way chromatographic cyclic process under critical operating conditions, that is, feed and elution solutions with the same total normality and percolation volumes. Local equilibrium theory is used to demonstrate the convergence of the system toward a periodic state and to calculate iteratively the instantaneous and asymptotic concentration profiles inside the separation column. One of the main results is that the calculated chloride composition on the inlet side of the column after the elution step is equal to the chloride composition in the feed solution.
