- Textile manufacturing: reducing and cleaning agent during fabric preparation, removing metal impurities that interfere with dyeing uniformity
- Leather processing and paper manufacturing: sequestrant controlling calcium hardness in process water
- Water treatment: complexes interfering metal ions before downstream chemical dosing steps
- It binds and immobilizes metal ions in solution.
