Abstract
The preparation and properties of ion chromatography sorbents based on Separon hydroxyethyl methacrylate copolymers are described. Sorbents with amino, ethylamino, diethylamino, dicyclohexylamino, diethanolamino and triethylamino functional groups were prepared by reaction of the appropriate amine with a precursor gel containing epoxy groups. Sorbents with the required ion-exchange capacity and additional cross-linking on column performance were studied. Examples of applications include the determination of nitrate in milk, separation of polythionates, etc.
