Diethylenetriaminepentaacetic acid pentasodium

1. EDTA-5Na can rapidly form water-soluble complexes with ions such as calcium, magnesium, iron, lead, copper, and manganese, especially exhibiting strong complexing ability with high-valence color-developing metals. Therefore, it is widely used as a stabilizing and enhancing agent in hydrogen peroxide bleaching; 2. a water softener; 3. an auxiliary agent in the textile printing and dyeing industry; 4. a primary standard reagent in analytical chemistry; 5. a chelating titrant, etc. 2. It is used as a hydrogen peroxide decomposition inhibitor in textile bleaching and paper pulp bleaching processes.
