If you want to know how to make deionized water, we would like to recommend you Lanlang mixed bed ion exchange resin.

Deionized water is produced by running tap water, spring water, or distilled water through an electrically charged resin. Usually, a mixed ion exchange bed with both positive and negative charged resins is used. Lanlang Cations and anions in the water exchange with H+ and OH- in the resins, producing H2O (water).

Because deionized water is reactive, its properties start to change as soon as it's exposed to air. Deionized water has a pH of 7 when it is delivered, but as soon as it comes into contact with carbon dioxide from the air, the dissolved CO2 reacts to produce H+ and HCO3-, driving the pH closer to 5.6.

Deionization does not remove molecular species (e.g., sugar) or uncharged organic particles (most bacteria, viruses).

The purity of deionized water depends on the source water. Deionized water is used when a soft solvent is needed. It is used for:

-cooling applications where it's important to avoid depositing minerals

-microbiology autoclaves

-many chemistry experiments involving ionic compounds

-washing glassware, especially the final rinse

-solvent preparation

-analytical blanks

-calibration standards

-in batteries
