where Cr is the concentration of component i in the liquid within the resin bead and Cai is the concentration of component i in the interstitial liquid. The distribution coefficient for a given ion or molecule will depend upon that component's structure and concentration, the type and ionic form of the resin and the other components in the feed solution.
