Deionizált

Deionizált water, often shortened to DI water, is water that has had nearly all of its mineral and salt ions removed. This process is achieved through ion-exchange resins, where positive ions like sodium and calcium are exchanged for hydrogen ions, and negative ions like chloride and sulfate are exchanged for hydroxide ions. These ions are then combined to form water. Deionizált water is also known as demineralized water.

The purity of deionizált water is significantly higher than that of regular tap water or even distilled water, as it removes dissolved ions that can interfere with various processes. Its primary uses are in applications where the presence of impurities can be detrimental. This includes laboratory work, where accurate chemical reactions are crucial, and in the manufacturing of electronics, pharmaceuticals, and cosmetics. It is also used in car batteries and steam irons to prevent mineral buildup and corrosion. While deionizált water is safe for consumption, it lacks the beneficial minerals found in natural water sources and may have a flat taste.
