Chromatographic Determination of the Selectivity Coefficients of Several
Inorganic Cations and Derivatives of Amines on the Sulfoacylated PS-DVB Beads
Cation-Exchanger
Abstract
The technique of synthesis of
sulfoacylated PS- DVB cation-exchanger with high degree of cross-linking was
given. The selectivity and efficiency of the separation of several inorganic
cations and derivatives of amines are investigated by ion chromatography with
conductometric detection. It is established that ion-exchange mechanism of the
separation is major for the alkali metals, ammonia and amines. From the
experimental data, the selectivity cofficients and Gibbs’s energies for all the
analytes were calculated.
