What is EDTA (Ethylene Diamine-Tetra-acetic Acid)
Ethylene Diamine-Tetra-acetic Acid (EDTA) is a synthetic chelating agent that is widely used in various industrial and medical applications. EDTA is a white, odorless, crystalline powder that is water-soluble.
EDTA forms strong chemical bonds with metal ions, including calcium, iron, and copper. This property makes it useful for a range of applications.
In the medical field, EDTA is used as an anticoagulant to prevent blood from clotting during blood collection and processing. It is also used in chelation therapy, a treatment for heavy metal poisoning, such as lead poisoning.
In industrial applications, EDTA is used to remove unwanted metal ions from solutions and prevent the oxidation of oils and fats in food products. It is also used in the production of detergents, textile manufacturing, and water treatment to remove hard water deposits.
Overall, EDTA is a versatile compound with many practical uses due to its ability to bind to metal ions and prevent their unwanted effects.
