DTPA 5Na Use
Agricultural
DTPA 5NA is a chelating agent trace elements in agriculture.
It offers essential nutrient elements to plants such as iron, zinc and manganese.
Such elments form stable complexes that are more easily absorbed by plant roots.
Water Treatment
DTPA 5NA sequesters or removes heavy metals in water. It prevents metal ions from reacting with other substances.
Paper
In pulp bleaching,DTPA 5NA 40% is a bleaching stabilizer for hydrogen peroxide, which has significant synergistic and stabilizing effects.
It is commonly used in the deinking process of waste paper, where the deinking agent is added simultaneously during pulping.
In addition, DTPA 5NA also has a strong complexing (chelating) effect on multivalent color developing metal ions,
transforming the color developing metal ions into colorless water-soluble complexes. Thereby it can improve the brightness of the pulp.
Industry
textile printing, dyeing industry auxiliaries, metal plating and electronics manufacturing.
It is helpful to remove or control metal impurities in solutions, which prevents unwanted reactions or product contamination.
Medicine
DTPA 5NA is commonly used as a contrast agent in medical imaging and metal chelation therapy.
DTPA 5NA removes heavy metals, such as lead, from the body.
It forms stable complexes with these metals, then excludes through urine.
