"Deionization" Natural Recordings by Native Speakers
Deionization is the process of removing ions and other impurities from water. It is used to produce pure water by exchanging ions in the water with ions in a chemical substance, such as resin, that selectively removes ions from the water. Deionization is often used in laboratories, hospitals, and other settings where highly purified water is required.
I apologize, but "deintevous" is not a real word in the English language. It's possible that it's a misspelling or a word that doesn't exist. If you meant to type a different word, please let me know and I'll be happy to help you with its meaning.
