Ethylenediaminetetraacetic acid (EDTA)

Ethylenediaminetetraacetic acid (EDTA) is a compound used mainly in medicine and industry to bind metal ions. In medical treatments, it is used to remove excess heavy metals from the body, such as lead or mercury, by binding to them so they can be excreted easily. In foods and cleaning products, EDTA helps prevent metal ions from causing spoilage or discoloration. Its ability to chelate (bind tightly) metals makes it useful for controlling metal-related reactions, ensuring stability, safety, and quality in various applications.
