Аннотация:We compare the ion exchange selectivity of phenoltype sorbents based on phenol formaldehyde
resins, products of condensation of diatomic phenols with formaldehyde, and crosslinked polymer based on
Cphenyl[4]resorcinarene resin, for cesium and rubidium ions. It is shown that phenol formaldehyde sor
bents are the ones most selective. The interaction of alkali metal cations with the anion of calix[4]arene is
investigated via quantumchemical modeling. It is shown that the selectivity toward cesium and rubidium
ions in ion exchangers of the phenolic type is not due to specific interactions of ions with phenolic groups.
