The term anion-exchange resin is mostly used in the case of solid organic polymers. 2, record 1, English, - anion%20exchanger
Record number: 1, Textual support number: 2 OBS
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

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
