Selectivity of Anion Exchange Resin Modified with Anionic Polyelectrolyte

Analytical Sciences, 1997
In order to change the ion-exchange selectivity of anion exchange resin, especially to make the ion-exchange of divalent anions more difficult, the surface of gel-type anion exchange resin was modified by the adsorption of an anionic polyelectrolyte: polycondensation product of sodium naphthalene sulfonate and formaldehyde.
