Chelating Resin is a specialized type of ion exchange resin designed to selectively bind specific metal ions through chelation — a chemical process where functional groups on the resin form multiple bonds with a single metal ion. Unlike standard cation exchange resins that rely on general electrostatic interactions, Chelating Resins are equipped with functional groups like iminodiacetic acid or aminophosphonic acid, which allow for stronger and more selective binding of heavy metals.

This makes Chelating Resin ideal for applications where precise separation or recovery of valuable or toxic metals is required. It is particularly effective in removing divalent and trivalent metal ions such as copper, nickel, lead, and cadmium from complex aqueous solutions. In industries like hydrometallurgy, electroplating, and electronics, this selective performance is essential for achieving high-purity outputs or complying with strict discharge standards.

Because of its ability to perform under varying pH levels and temperatures, Chelating Resin is widely used in water treatment, chemical recovery, and metal purification systems. Additionally, it offers the advantage of regenerability and long operational life, making it a cost-effective and environmentally friendly solution for industrial metal ion separation.

Macroporous Styrene Chelating Resin D403

D403 is a chelating ion exchange resin product with imine diacetic acid group [-N-(CH2COOH)2] on the benzene ring of a styrene-divinylbenzene copolymer sphere with a large pore structure. The selectivity of ions is similar to EDTA. It is higher than strongly acidic or weakly acidic cation exchange resins. When covalently presents monovalent ions and divalent metal ions in the solution, it only selectively adsorbs divalent ions. This product is suitable for deca2+ in dielectric salt water. This product is suitable for dielectric In the case of brine, Mg2+ refined brine is also used in wastewater treatment and recovery of precious metals.

Macroporous Styrene Chelating Resin CH520

CH520 macroporous styrene chelating resin is a cation exchange tree with a phosphoramidite functional group. This resin is basically chelating to all divalent metal ions, especially for alkaline earth metals with special selectivity. CH520 is an ideal resin suitable for salt water softening. It can be used to remove divalent metal cations from industrial wastewater and other industrial water. CH520 is mainly used for refining secondary brine in the process of making caustic soda by ion membrane method. It can reduce calcium and magnesium ions in secondary brine to 20 ppb, and resin exchange Both capacity and mechanical strength are better than similar aminolin acid resins abroad. In addition, D418 can also be used for the recovery of heavy metals in electroplating wastewater.

About Our Company

How does Chelating Resin contribute to environmentally responsible manufacturing?

Chelating Resin supports eco-friendly and sustainable industrial practices by offering an efficient and selective method for removing and recovering heavy metals from wastewater and industrial process streams. Instead of using excessive amounts of chemicals for precipitation or neutralization, chelating resins can selectively capture target metal ions while leaving other components unaffected. This minimizes chemical waste and reduces sludge generation.

The ability to regenerate Chelating Resin multiple times through acid or base washing extends its usable life and reduces the need for frequent replacement, leading to significant waste reduction. Additionally, many industries can recover valuable metals like nickel or cobalt directly from the resin, turning waste into resource and enhancing economic value.

Because our Chelating Resin is produced under strict environmental standards using low-emission processes, it not only helps customers reduce their environmental footprint but also complies with global regulatory frameworks such as RoHS and REACH. It is an excellent solution for companies seeking high-performance separation technology without compromising on sustainability goals.

What are the industrial applications of Chelating Resin?

Chelating Resin is utilized across a variety of industries due to its unique ability to selectively bind and recover metal ions from aqueous systems. In water treatment, it is commonly used to remove trace levels of heavy metals like lead, copper, and mercury to meet environmental discharge regulations and ensure safe reuse of process water.

In hydrometallurgy, Chelating Resin plays a vital role in the selective recovery of valuable metals such as cobalt, nickel, and rare earth elements from leachates. It enhances metal recovery efficiency while minimizing contamination from undesired ions. Similarly, in the electronics and semiconductor industries, it is used to purify processing solutions by removing trace metals that can interfere with product performance.

The resin also finds applications in pharmaceutical manufacturing and biotechnology, where it helps in the purification of biologically active compounds by removing metal contaminants that could affect biological activity or safety. Because of its ability to be regenerated and reused without significant degradation, Chelating Resin ensures long-term efficiency and lower operational costs, making it an ideal choice for sustainable industrial operations.
