deionized water distilled
Deionized water refers to pure water that has undergone special treatment to remove all impurities in ionic form from water. Common preparation methods include ion exchange resin method, reverse osmosis method, and electro deionization method. Among them, the ion exchange resin method uses cation and anion exchange resins to remove electrolytes and other ions from water, while the reverse osmosis method selectively intercepts ions in water through membrane permeability. These methods can significantly reduce the conductivity of water, meeting the needs of fields such as laboratories and the electronics industry.
