What is Macroporous Styrene Chelating Resin D403 used for?

D403 is primarily used for selective removal and recovery of heavy metal ions, such as copper, nickel, zinc, cobalt, and rare earth elements, from industrial wastewater and hydrometallurgical solutions.

How does D403 chelating resin work?

D403 contains functional chelating groups (usually aminophosphonic or iminodiacetic groups) that form stable complexes with metal ions. This selective binding allows it to efficiently capture specific metals even in the presence of competing ions.

What are the main advantages of D403 resin?

D403 offers high selectivity, excellent adsorption capacity, mechanical strength, and chemical resistance in both acidic and alkaline environments. Its macroporous structure provides fast ion diffusion and high efficiency in dynamic column operations.

In which industries is D403 commonly applied?

D403 is widely used in electroplating wastewater treatment, electronics manufacturing, mining and metallurgy, rare earth extraction, and chemical production where precise metal ion separation is essential.

How is D403 resin regenerated after saturation?

After metal saturation, D403 can be regenerated using acid solutions (e.g., HCl or H₂SO₄) to desorb the metal ions, followed by rinsing with deionized water. The resin can then be reused in multiple cycles with minimal performance loss.

Is D403 safe and environmentally friendly?

Yes, D403 is non-toxic and stable under normal operating conditions. When used properly, it helps reduce environmental pollution by recovering valuable metals and minimizing toxic metal discharge into natural water sources.

Óvintézkedések

A gyantát nedves állapotban kell tárolni. A legjobb hőmérséklet 0 ℃ felett van. A gyantát zárt térben kell tárolni, vagy 5%-os vagy annál magasabb sótartalmú vizet kell hozzáadni, ha hosszabb ideig nem használják. Szállítás közben fagyállónak kell lennie. Ne helyezzen nehéz tárgyakat a gyantára, mert ütközhet.

A feldolgozáshoz általában lúg-víz-sav-víz áramlási útvonal szükséges. A szigorú követelmény három keringtetést igényel a végső ionkenel elérése előtt.

Különböző transzformációs expanziós sebességeket kell figyelembe venni, hogy elegendő helyet hagyjunk a gyanta túlcsordulásának megakadályozására és a megfelelő folyadékszint magasságának biztosítására; Az oszlop átmérőjének arányának ésszerű tartományon belül kell lennie, és el kell kerülni az előfeszítő áramot; Nedvesen töltött oszlopot vagy visszaöblítést kell használni a gyantaréteg belsejében lévő buborékok eltávolítására.

Mielőtt a folyadék a gyantaoszlopba kerülne, olyan lépéseket kell végrehajtani, mint a flokkuláció, szűrés vagy homokszűrés, hogy a szuszpendált szilárd anyagok ne tömítsék el a gyanta pórusait.

Az oszlopban lévő, hosszú ideig nem használt gyantát mosás után az oszlopon kívül kell tárolni, vagy sós vizet kell hozzáadni a sóálló közeghez, miközben a folyadékszintet nem szabad kiszáradni a szokásos visszamosással, hogy a gyanta fellazuljon agglomeráció esetén.
