Application

DTPA-5Na can rapidly form water-soluble complexes with metal ions such as calcium, magnesium, iron, lead, copper and manganese, especially for high-valent state of metal ions complex ability, therefore it is widely used: 

1) Hydrogen peroxide bleach enhancer stabilizer

2) Water softener

3) Textile printing and dyeing industry auxiliaries

4) Color photographic material processing processing bleach fixing solution

5) Analytical chemistry of the reference reagent

6) Chelating titrant

7) Daily chemical industry

8) Cosmetics industry
