Abstract: The exchange of calcium and potassium ions on the cross-linked pectin with different content of methoxyl groups was studied. The exchange equilibrium was classified according to the selectivity coefficient and the Rothmund—Kornfeld equation. In consonance with the assumption, the lower was the degree of esterification of the cross-linked pectin, the higher was the selectivity to calcium ions. The same dependence was found with a synthetic carboxyl cation-exchanger Zerolit 226 used as a reference.
