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.

New Anion Exchange Resins for Improved Separations of Nuclear Materials [PDF]
, 1999 We are developing multi-functional anion-exchange resins that facilitate anion uptake by carefully controlling the structure of the anion receptor site. We are attempting to determine if the precepts of ''bite size,'' ''preorganization,'' and ''bidentate'
