A resin that holds and swaps only cations. Cation resins contain hydrogen ions (H+) to remove positively-charged, dissolved ionic contaminants such as calcium, sodium, magnesium and potassium.  4, record 1, English, - cation%2Dexchange%20resin

Record number: 1, Textual support number: 1 CONT

Other important applications of ion exchange are water softening and the demineralization of water. ... In the second [application], 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.  5, record 1, English, - cation%2Dexchange%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 1, French, - r%C3%A9sine%20%C3%A9changeuse%20de%20cations

An exchanger containing cations which are exchangeable for other cations present in the solution.  2, record 2, English, - cation%20exchanger

The term cation-exchanger resin may be used in the case of solid organic polymers.  2, record 2, English, - cation%20exchanger

Record number: 2, Textual support number: 2 OBS

The early cation exchangers were naturally occurring zeolites but these have been almost completely superseded by the synthetic organic ion exchangers. The synthetic cation exchangers are classified into two main groups, the weak cation exchangers and the strong cation exchanger. In the former the main functional groups are carboxylic acid groups and in the latter they are sulphonic acid groups.  4, record 2, English, - cation%20exchanger
