There are two main categories of anion exchanger - the strong base exchangers and the weak base exchangers. A typical strong anion exchanger is prepared from the polymerization of styrene and divinylbenzene, followed by chloromethylation and treatment with an appropriate secondary or tertiary amine ... The weak anion exchanges contain a mixture of primary secondary and tertiary amino groups. They are produced by condensing aliphatic amines with either epichlorohydrin or ethylene dichloride ...  4, record 1, English, - anion%20exchanger

A resin that holds and swaps only anions. Anion resins contain hydroxyl ions (OH-) to remove negatively-charged, dissolved ionic contaminants such as carbonates, bicarbonates, sulfates, nitrates and silica.  5, record 2, English, - anion%20exchange%20resin

Other important applications of ion exchange are water softening and ... demineralization ... [in which] all ionic impurities contained in water are removed by exchange for hydrogen and hydroxyl ions during passage of the water successively through cation- and anion-exchange resins in the acid and base form.  6, record 2, English, - anion%20exchange%20resin

Les échangeurs d'ions [...] [utilisés] dans l'adoucissement des eaux [...] sont maintenant constitués par des résines synthétiques. Ces résines échangeuses de cations et d'anions sont des composés organiques, de structure macro-ionique [...]. C'est ainsi qu'une eau naturelle contenant des impuretés ioniques [...] échange, en passant sur ces résines, les ions qu'elle renferme contre des ions H- ou OH- lesquels se combinent en donnant de l'eau; celle-ci se trouve donc purifiée (désionisée).  4, record 2, French, - r%C3%A9sine%20%C3%A9changeuse%20d%27anions

Para que el intercambio iónico resulte económico en el tratamiento avanzado de aguas residuales, convendrá utilizar productos regeneradores y restauradores que eliminen tanto los aniones inorgánicos como el material orgánico de la resina agotada. Los restauradores físicos y químicos, cuya aplicación en la separación de materias orgánicas de resina se ha realizado con éxito, son hidróxido de sodio, ácido clorhídrico, metanol y bentonita.  1, record 2, Spanish, - resina%20de%20intercambio%20ani%C3%B3nico
