What Is EDTA in Chemistry?

Scientific terms regularly become a part of our everyday vernacular as Americans. Whether it's plasma, magnetic fields, or even hydrogen fuel, Americans are intrigued and interested by the sciences. The term EDTA however, still confuses some people.

  1. Definition

    • EDTA in chemistry is an acronym for ethylenediaminetetraacetic acid. This compound works by bonding with metal ions, and is commonly used in a number of products for a variety of reasons.

    Textiles

    • EDTA is used in the clothing industry because it stops metal ions from interfering with the quality and color of dyes.

    Medicine

    • In the medical field, EDTA is used to remove excess iron from the blood stream, and it can help in overcoming difficulties caused by multiple blood transfusions.

    Environmental Considerations

    • EDTA was widely used for a long period of time, but the problem is that it has since been recognized as a great environmental pollutant. Different versions of the chemical have since been developed that are more biodegradable.

    Popular Culture

    • EDTA is so commonplace that in the hit action movie Blade is was used as a weapon against vampires, since the EDTA caused bizarre chemical reaction in the undead's blood.
