EDTA solution is widely used in various industries due to its strong ability to bind metal ions. In medicine, it is used in chelation therapy to treat heavy metal poisoning, such as lead or mercury toxicity, by forming stable complexes that the body can excrete. It is also added to blood collection tubes to prevent clotting by binding calcium ions, making it essential in laboratory diagnostics.

In the food industry, EDTA solution acts as a preservative by deactivating metal ions that can catalyze spoilage and discoloration, helping to extend shelf life in products like dressings, sauces, and canned goods. It is also used in cosmetics and personal care products to improve stability and prevent degradation caused by trace metals.

In industrial applications, EDTA is used for water softening by sequestering calcium and magnesium ions, improving the efficiency of detergents and cleaning agents. It is also employed in pulp and paper production, textile processing, and boiler water treatment to control metal-induced reactions. Additionally, in agriculture, it helps deliver micronutrients like iron to plants in a bioavailable form, especially in alkaline soils.
