Deionized WaterWhat is deionized water?
Deionized water (also called DI water) is a type of purified water in which mineral ions are removed. Tap water is usually contaminated with different ions from the soil, pipes, or other sources. Some of these common ions include calcium, sodium, copper, iron, chloride, and bromide
Why is it necessary to use deionized water?
Pure water is essential in different applications like laboratory experiments, drugs, cosmetics, electronics manufacturing, food processing, metallurgy, and other industrial processes. Impurities in water may cause interference which may cause undesirable results. Water contaminated with ions is also more electrically conducive and may not be suitable for some applications.
What are the common uses of deionized water?
Aside from its popularity in medical applications, it is also popular in scientific and industrial settings. For one, it is used extensively as a medium or additive in microbiology experiments, pharmaceutical production, and cosmetic manufacturing. It is also used to top up lead batteries. Prior to engine usage, deionized water is cooked in an autoclave o kill off bacteria and viruses. Deionized water is also applied in steam ironing to prevent mineral residues from staining clothes.
What size containers does deionized water come in?
ChemWorld stocks 1 gallon, 20 liter boxes, an 55 gallon containers of DI water
How is water deionized? What are its different processes?
Ions from ordinary water are removed via ion exchange process, which occurs at the binding sites of exchange resin beads. With the resin‰Ûªs greater affinity for other ions, cations (positively charged ions) and anions (negatively charged ions) are exchanged for hydrogen (H+) and hydroxyl ions (OH-) respectively. Once the resin bed is depleted of exchange capacity, it is regenerated with concentrated acid and caustic soda which strips away accumulated ions. By this physical displacement, hydrogen or hydroxyl ions are left in their place.
