Ferric sodium edetate, also known as sodium ferric ethylenediaminetetraacetate, is a complex compound formed by the chelation of ferric ion (Fe3+) with ethylenediaminetetraacetic acid (EDTA) and subsequent neutralization with sodium hydroxide (NaOH).It is a water-soluble, crystalline solid with a reddish-brown color.

Ferric sodium edetate is commonly used in various industries and applications due to its properties as a chelating agent.As a chelator, it has the ability to bind to and form stable complexes with metal ions, especially ferric (Fe3+) ions.This property makes it useful in several areas, including:

Industrial Applications: Ferric sodium edetate is employed in various industrial processes such as metal plating, water treatment, and textile dyeing.It helps in metal ion sequestration and stabilization, preventing unwanted reactions and improving the efficiency of these processes.

Agriculture and Horticulture: Ferric sodium edetate is used as a micronutrient fertilizer in agricultural and horticultural practices.It serves as a source of iron (Fe) for plants, which is essential for their growth and development.The chelated form of iron provided by ferric sodium edetate allows for improved absorption and utilization by plants.

Food and Beverage Industry: Ferric sodium edetate is sometimes used as a food additive, primarily as an iron fortifier.It can be added to certain food products to increase their iron content and address iron deficiencies in the diet.

The use of ferric sodium edetate, particularly in food and beverage applications, is subject to regulations and guidelines set by relevant authorities to ensure safety and proper usage levels.
