Stoichiometric mass-action ion-exchange model explicit isotherms for mono-, di-, tri- and tetrameric ions
(1995)Analytical isotherms for the unhindered stoichiometric mass-action ion exchange of monomeric, dimeric, trimeric and tetrameric ions are derived. The linear increase in oligomer charge from 1 to 4 leads to an exponential ...
