EDTA is widely used in various industries due to its ability to bind metal ions. In medicine, it is utilized as a chelating agent to treat heavy metal poisoning, such as lead or mercury, by forming stable complexes that the body can excrete. In the food industry, EDTA acts as a preservative, preventing oxidation and discoloration by sequestering metal ions that catalyze these reactions. In water treatment, it helps to soften water by binding calcium and magnesium ions, reducing scale formation in pipes and boilers. Additionally, EDTA is employed in cosmetics to stabilize formulations and enhance the shelf life of products by preventing metal-induced degradation. In analytical chemistry, it is a key reagent in complexometric titrations for determining metal ion concentrations. Its versatility in binding metals makes it indispensable across these fields.
