| Abstract: | The chemical stability in aggressive media of two types of strong base anion exchangers was studied. The anion exchangers were a commercial Amberlite IRA-400 with a styrene structure and an unconventional resin obtained by the quaternization of a 4-vinylpyridine: 8% divinylbenzene copolymer with methylchloride. The presence of the quaternary nitrogen atoms in or out of the aromatic ring had a great influence on the chemical stability of the ion exchangers. |
