The characteristic nature of ion-binding of much charged polyions has been investigated mainly on the basis of the Poisson-Boltzmann (P.B.) equation and partly through the conductance experiment. In general, the ion-binding can be classified into two types, the φ-binding and the P-binding. The former is due to the electrostatic field around polyions, while the latter is due to the short-range interaction between ionized groups of polyions and salt-ions. Through the theoretical analysis of non-linear property of the P.B. equation, we have found, for every shape of polyions, the strong φ-binding of counterions which greatly depresses the polyion-charge within a thin ion-condensation phase around the polyion.
