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.

Precautions

Resin should be wet state preservation. The best temperature is above 0℃. Resin should be put into a closed space or add in salt water of 5% or above if not used for a long time.Should be anti-freezing during transportation. Do not place heavy objects on the resin in case being crashed.

Generally requires alkali- water - acid - water flow path for processing. Strict requirement needs three circulation before coming to final ion kenel.

Need to consider different transformation expansion rate to set aside enough space to prevent resin overflow and ensure the appropriate liquid level height; Column diameter ratio should be within a reasonable range and avoid bias current; Use wet packed column or back-flushing to wash away bubbles inside resin layer.

Before liquid going into the resin column, steps as flocculation, filtration, or sand-filtration should be taken so that it doesn’t jam resin pore with suspended solids .

Resin inside the column that hasn’t been used for a long time should be storaged outside of the column after washing, or adding salt water in the salt resistant medium while keeping liquid level not dehydrated with usual backwashing to loosen resin in case of agglomeration.
