Studies on chelating resins-I General equation for the calculation of the protonation constants of chelating resins.
A general equation has been derived which describes the protonation equilibria of basic groups attached to an insoluble polymer matrix. The derivation is based on the application of the charge and mass-balance equations. When the relationship obtained is applied to water-soluble ligands, it reduces to the well-known Schwarzenbach equation for titration of polybasic acids.
