Classification and fundamental properties of ion exchangers

According to the literature cited [1-11,53-57] the ion exchangers can be classified, from the chemical point of view, as inorganic (very seldom used in biochemistry) and 

It is a pity that these ion exchangers, which have been proved to be effective for the separation of biopolymers are not yet produced commercially. 

It is a reversible process and the direction of the reaction is affected not only by the 

The degree of such an exchange under static conditions (Eq. 1), in a grain of ion exchange resin in contact with an electrolyte solution, is governed both by Donnan equilibria (which also control the swelling of the particle) and by the affinity of ions to the exchanger. It ean be expressed quantitatively by Samuelson s equation [58] 

Giddings [62] generally defines H, in liquid chromatography, as the function of linear flow rate u of the mobile phase in this form
