use

1. Complexing agent: It can form metal complexes with a variety of metals for analysis and determination, and separate rare metals. It can also be used to extract individual metals from rare metals.

2. Catalyst: In the production of polyurethane foam, it can be used as a foaming catalyst, which can foam immediately and gel quickly.

3. Stabilizer: In polystyrene production, it can be used as a stabilizer.

4. Detergent: In the water vapor generator system of nuclear reversal, it can be injected into the steam-water cycle as an aqueous solution to remove the scale and corrosive substances between the walls, without affecting the efficiency during the addition process.

5. Electroplating agent: In non-toxic plating, it can speed up deposition.

6. Color photographic developer: In color photographic development, it is one of the important ingredients and can be used to prevent the generation of precipitation during development. Nitrogen triacetic acid is a substitute for tripolyphosphate, and has also been paid attention to solving the problem of eutrophication of water in synthetic detergents.

7. Polycarboxylic acid chelating agent: because of its small molecule, it can chelate more metals and has strong biodegradability. Add a certain amount of reducing agent and pH adjuster to the subnitrotriacetic acid to remove Fe2O3, hematite oxide has excellent effect.
