Application:

Product Uses:
- In industry, EDTA 4Na is mainly used to isolate metal ions in aqueous solutions.
- In the textile industry, it prevents metal ion impurities and changes the color of the dyeing product.
In the pulp and paper industry, EDTA inhibits the ability of metal ions.
- Reduce hardness in water.
- Used in the separation of lanthanum group metals.
- Use in shampoos, detergents.
- Used for titration:
- In the aquaculture industry, EDTA 4Na is used to control water sources, it treats organic residues and impurities that exist
in the water and also has the effect of softening the water in shrimp and fish hatcheries with hardness due to heavy metal
contamination such as aluminum, iron, calcium, magnesium.:
