EDTA-CuNa2 is a chemical compound that belongs to the family of chelating agents and contains copper. Its chemical name is Ethylenediaminetetraacetic acid copper disodium salt hydrate.
Chemical Property:
EDTA-CuNa2 is a derivative of ethylenediaminetetraacetic acid (EDTA), which is a polydentate ligand. This means that EDTA has multiple sites (atoms with lone pairs of electrons) available for binding with metal ions. In the presence of copper ions (Cu2+), the EDTA-CuNa2 molecule can form stable, water-soluble complexes with the copper ions. The chelation process helps to keep the copper ions in a soluble and bioavailable form. The chemical formula for EDTA-CuNa2 is C10H12N2O8CuNa2. And its CAS number is 14025-15-1.
Here are some of the main application areas for EDTA-CuNa2:
EDTA-CuNa2 is used in agriculture to supply plants with a readily available form of copper and to address copper deficiencies in soils. Here are some key areas of application in agriculture:
1. Agriculture:
Micronutrient Fertilizer: EDTA-CuNa2 is used as a component in micronutrient fertilizers. These fertilizers are formulated to provide essential micronutrients, including copper, in a form that is easily absorbed by plants. Copper is involved in various physiological processes in plants, such as photosynthesis, and its deficiency can lead to stunted growth and reduced yields.
Soil Amendment: In soils where copper deficiencies are identified, EDTA-CuNa2 can be applied as a soil amendment. The chelating property of EDTA helps in keeping copper in a soluble form, making it more available for plant uptake. This ensures that plants receive an adequate supply of copper for their metabolic processes.
Foliar Sprays: EDTA-CuNa2 can be applied as a foliar spray directly onto plant leaves. This method allows for rapid absorption of copper by the plants. Foliar application is particularly useful when there is an immediate need to address copper deficiencies or when soil conditions limit the availability of copper to plants.
Hydroponics: In hydroponic systems, where plants are grown in nutrient solutions without soil, EDTA-CuNa2 can be added to provide a controlled and balanced supply of copper to the plants.
Seed Treatment: Some formulations of micronutrient fertilizers containing EDTA-CuNa2 are used for seed treatment. Treating seeds with such formulations ensures that the emerging seedlings have access to essential copper from the early stages of growth.
2. Medicine:
EDTA and its derivatives, including EDTA-CuNa2, are used in chelation therapy, a medical treatment for removing heavy metals from the body. The chelating properties help in binding and eliminating excess metals, such as lead or mercury, from the bloodstream.
3. Analytical Chemistry:
EDTA-CuNa2 is widely used in analytical chemistry for titrations to determine the concentration of metal ions, particularly copper. It forms stable complexes with copper ions, allowing for accurate and precise measurements.
4. Water Treatment:
Chelating agents like EDTA-CuNa2 are used in water treatment processes to sequester metal ions and prevent them from causing issues such as corrosion or scale formation in pipes and equipment.
5. Industrial Processes:
In various industrial processes where the presence of copper ions may interfere with the efficiency of the process or the quality of the final product, EDTA-CuNa2 can be employed to chelate and remove these ions.
6. Photography:
EDTA-CuNa2 is used in the photography industry to control the activity of metal ions in photographic solutions, contributing to the stability and quality of the development process.
7. Textile Industry:
In the dyeing and textile industry, EDTA-CuNa2 is utilized to control the levels of metal ions, particularly copper, which can affect the color and quality of the final textile product.
It's important to note that while copper is essential for plant growth, excessive levels can be harmful. Therefore, the application of EDTA-CuNa2 or any copper-containing fertilizer should be based on soil testing and careful consideration of the specific needs of the crops being grown.
