应用

HEDTA 3NA is mainly used as metal complexing agent, styrene-butadiene rubber activator, and photosensitive material bleaching and fixing fluid; HEDTA 3NA can also be used as a cleaning agent. The pulp bleaching purpose is similar to HEDTA. HEDTA 3NA is gradually used in textiles, agriculture (pesticides, and can be used in alkaline soils). Iron fertilizer (HEDTA-Fe), medicine (used as an antidote for iron), leather, papermaking, cosmetics, water treatment, electroplating, chemical plating (especially in silver plating), etc. Especially in rare earth It has very important applications in refining and purification.
