8.EDTA-2Na Main Uses:
EDTA is an important complexing agent for complexing metal ions and separation of metals, the materials used for processing color photographic materials, wash bleach fixer, and dyeing auxiliaries , fiber processing agents, cosmetic additives, pharmaceuticals, food, agriculture, chemical fertilizer production, blood anticoagulant, complexing agents, detergent, stabilizer, synthetic rubber, polymerization initiator and quantitative analysis of heavy metals etc.. SBR polymer in the lead chloride reduction system, EDTA disodium as the active agent component, mainly for the complexation of iron ions, control the polymerization rate.
