The amine-phosphate-based chelating gene ion exchange resin product, known as D409 chelate resin, was introduced into the macropores styrene-divinyl crosslinking copolymerization sphere. Divalent metal ion exchange is good in D409 chelate resin. Compared to Na2+ ion exchange adsorption, adsorption on Ca2+, Mg2+, and other divalent metals is substantially larger.

Ion-exchange membranes are therefore frequently utilized in the manufacturing of purified secondary aqueous saline solution and caustic soda apparatus. For refined secondary brine with a salty Sr2+ content of less than 0.5 ppm, D409 chelating resin is advised. It has free chlorine-resistant qualities, but to prolong the resin's lifespan, the free chlorine in the brine should be eliminated before it enters the tower.

Key applications for D409 chelating resin:
The divalent metal ions can be effectively eliminated by chelating resins with aminophosphonic genes. Purified secondary brine is currently frequently used in the chlor-alkali industry. Concurrently, as well as for the heavy metals, hydrometallurgy, industrial wastewater treatment, and environmental protection sectors.
