Deionization is the process of removing ions from a solution. The word is spelled with "d", "e", "i", "o", "n", "i", "z", "a", "t", "i", "o", and "n". In IPA phonetic transcription, it is: diːaɪənɪˈzeɪʃən. The stress falls on the second syllable. The first syllable is pronounced like the word "dee", but with a longer "i". The second syllable has a slightly shorter "i" sound followed by a long "aɪ". The last syllable rhymes with "station".
Deionization refers to the process of removing ions from a solution or a substance in order to eliminate any forms of electric charge present. It is a chemical treatment technique commonly used in water purification and various industrial processes to produce highly purified water or solvents.
Deionization typically involves the use of ion-exchange resins, which are specific polymer materials that possess an affinity for ions in water. These resins contain functional groups capable of attracting and replacing ions present in the water with H+ and OH- ions. As a result, the positive and negative ions in the water are effectively removed, resulting in deionized water.
The deionization process involves utilizing an ion exchange column or bed, where water passes through the resin material. The ions present in the water interact with the resin, and through ion exchange, they are replaced with hydrogen and hydroxide ions. This interaction neutralizes the electrical charge, hence producing deionized water.
Deionized water finds applications in various sectors including laboratory work, pharmaceutical manufacturing, electronics, and power plants, where the presence of impurities or charged particles can be detrimental. It is highly desirable to have deionized water in these industries to prevent any potential damage to sensitive equipment, ensure accurate experimental results, and avoid product contamination.
In summary, deionization is the process of removing ions from a solution through ion exchange to achieve a highly purified and charge-free substance, commonly used in water purification and various industrial applications.
The word "deionization" comes from the combination of two parts: "de-" and "ionization".
1. "De-" is a prefix of action indicating negation, reversal, removing, or undoing. In this case, it suggests the removal or elimination of ions.
2. "Ionization" refers to the process of forming ions by adding or removing electrons from an atom or molecule. It is derived from the noun "ion" which, in turn, comes from the Greek word "ion" meaning "going" or "one who goes".
So, "deionization" literally means the process of removing or eliminating ions.
