1. Introduction

EDTA-2NA is a compound derived from ethylenediamine, formaldehyde, and sodium cyanide. Its chemical formula is C10H14N2Na2O8. The disodium salt form of EDTA makes it highly water-soluble and facilitates its utilization in various aqueous systems. Due to its strong chelating properties, EDTA-2NA finds extensive applications in numerous industries.

2. Understanding Chelation

Chelation is a chemical process in which a chelating agent binds to metal ions, forming a complex that prevents the metal ions from participating in chemical reactions or causing undesirable effects. EDTA-2NA has the ability to chelate a wide range of metal ions, including calcium, magnesium, iron, copper, and zinc. The formation of these stable complexes helps in controlling and manipulating metal ions in different applications.

3. The Properties of EDTA-2NA

EDTA-2NA possesses several notable properties that contribute to its effectiveness as a chelating agent. Firstly, it is highly soluble in water, enabling its easy integration into various aqueous systems. Additionally, EDTA-2NA is stable over a wide pH range, allowing it to function effectively in acidic as well as alkaline environments. Its versatility and stability make it suitable for a diverse range of applications.

4. Applications in Industrial Processes

Metal Cleaning and Plating

One of the significant uses of EDTA-2NA is in metal cleaning and plating processes. It is employed to remove unwanted metal ions, scale, and deposits from metal surfaces. By forming complexes with the metal ions, EDTA-2NA aids in their removal, resulting in cleaner and brighter metal surfaces. Moreover, it is also used in electroplating baths to enhance the deposition of metal coatings.

Textile and Dyeing Industry

In the textile and dyeing industry, EDTA-2NA is utilized as a sequestering agent. It helps in controlling metal ions present in the dyeing process, preventing their interference with dyes and improving color retention. EDTA-2NA ensures better dye penetration and uniform color distribution, leading to enhanced dyeing efficiency and quality.

Pharmaceutical and Medical Applications

EDTA-2NA plays a crucial role in pharmaceutical and medical applications. It is used in chelation therapy to treat heavy metal poisoning, such as lead and mercury toxicity. By forming stable complexes with the toxic metal ions, EDTA-2NA helps in their removal from the body, reducing the harmful effects. Additionally, it is also utilized as a preservative in certain medications to prevent the degradation of active ingredients.

Water Treatment

Water treatment processes rely on EDTA-2NA for its ability to sequester metal ions and prevent their detrimental effects. It is used in boiler water treatment to control scale formation caused by calcium and magnesium ions. Furthermore, EDTA-2NA finds application in wastewater treatment to remove heavy metals and facilitate the purification of water.

5. Environmental Considerations

While EDTA-2NA offers numerous benefits, it is important to consider its environmental impact. As a chelating agent, it forms stable complexes with metal ions, which can make the removal of heavy metals from wastewater challenging. Therefore, it is crucial to adopt appropriate treatment methods to ensure the proper disposal or remediation of EDTA-2NA complexes.

6. Safety Precautions and Handling

When working with EDTA-2NA, it is essential to follow safety precautions. Always wear appropriate personal protective equipment (PPE), such as gloves and goggles, when handling this compound. Additionally, ensure proper ventilation in the working area to avoid inhalation of fumes or dust particles. Store EDTA-2NA in a cool, dry place, away from incompatible substances.


  1. Is EDTA-2NA harmful to the environment?

    EDTA-2NA can have an impact on the environment if not properly managed. It is important to handle and dispose of it responsibly to minimize any potential adverse effects.

  2. Can I use EDTA-2NA at home for cleaning?

    EDTA-2NA is primarily used in industrial and commercial applications. It is not recommended for use at home without proper knowledge and understanding of its handling and potential risks.

  3. What are the alternatives to EDTA-2NA?

    There are other chelating agents available, such as citric acid and gluconic acid, which can be used as alternatives to EDTA-2NA in certain applications.

  4. Can EDTA-2NA be used in food and beverages?

    EDTA-2NA is not intended for direct consumption in food and beverages. It is primarily utilized in industrial processes and should be handled accordingly.

  5. Where can I obtain EDTA-2NA for industrial use?

    EDTA-2NA can be sourced from chemical suppliers or manufacturers specializing in chelating agents.


EDTA-2NA, a versatile chelating agent, plays a vital role in numerous industries and applications. Its ability to form stable complexes with metal ions makes it valuable in metal cleaning, plating, textile dyeing, pharmaceuticals, and water treatment. However, it is crucial to consider its environmental impact and handle it responsibly. By understanding the properties and applications of EDTA-2NA, industries can harness its potential to optimize their processes while prioritizing safety and sustainability.
