How do chelating resins differ from conventional ion exchange resins?

Chelating resins have functional groups that form chelates with metal ions, giving them higher metal ion selectivity than conventional ion exchange resins and allowing them to remove or recover only specific metals even from solutions containing multiple metals. They are used in wastewater treatment, metal ion removal, secondary brine purification, and more.

Which metal ions can Samyang's TRILITE® chelating resins selectively remove?

Depending on the type of functional group, Samyang's TRILITE® chelating resins selectively remove chromium, nickel, copper, tin, antimony, rhodium, boron, mercury, silver, and more, and can separate only the target metal even from mixed-metal solutions. The suitable product is selected according to conditions such as target metal concentration, coexisting ions, pH, and process temperature.

Which chelating resins are available for boron removal, and how do they differ?

Samyang's TRILITE® CLR-B3 and CLR-B3UP both use a glucamine functional group with high boron selectivity. CLR-B3 is for general wastewater treatment where high concentrations of anions coexist, while CLR-B3UP, with low TOC leaching (ΔTOC < 5 ppb), is for boron polishers in ultrapure water production.

Is there a chelating resin that selectively removes only mercury (Hg) from wastewater?

Yes. Samyang's TRILITE® CLR-10 uses a thiouronium functional group with high mercury adsorption capacity and low adsorption of other heavy metals, making it well suited to selectively treating mercury in wastewater.

Which product is suitable for selectively removing heavy metals such as chromium and nickel separately from alkali metals?

Samyang's TRILITE® CLR-20 is a chelating resin with a polyamine functional group that has excellent selectivity for heavy metals such as chromium and nickel but does not adsorb alkali metals (Na⁺, K⁺) or alkaline earth metals (Ca²⁺, Mg²⁺), making it suitable for separating only heavy metals when large amounts of these ions coexist.

Key Features

TRILITE® chelating resins are ion exchange resins that can strongly adsorb and
separate specific metal ions. Because they have functional groups that form chelates
with metal ions, their selectivity for specific metal ions is far higher than
that of conventional ion exchange resins.

They are widely used from heavy metal removal in industrial wastewater to secondary brine purification, which removes calcium and magnesium from brine. Recently, their use has expanded to boron polishers, increasing their role in the ultrapure water market.

FAQ

Q. How do chelating resins differ from conventional ion exchange resins?

Chelating resins have functional groups that can form chelates with metal ions,
giving them higher selectivity for metal ions than conventional ion exchange resins.
Thanks to this selective binding, they can remove or recover only specific metal ions even from solutions containing a mixture of metal ions. They are used in wastewater treatment, metal ion removal, secondary brine purification, and more.
Q. Which metal ions can Samyang's TRILITE® chelating resins selectively remove?
The metal ions targeted by Samyang's TRILITE® chelating resins vary depending on the type of functional group. They are used to remove a variety of heavy metals and trace metal ions such as chromium, nickel, copper, tin, and antimony; in particular, their ability to selectively separate target metals even from mixed-metal solutions distinguishes them from conventional strong acid and weak acid ion exchange resins.
Since the suitable functional group depends on the exact target, concentration, and coexisting ion conditions, sharing your specific conditions will allow us to recommend the right product.
- Selectively removable ions: Chromium, nickel, copper, tin, antimony, rhodium, boron, mercury, silver, and alkali/alkaline earth metals (sodium, calcium, etc.)
- Application conditions to confirm: Target metal concentration, type and concentration of coexisting ions, pH, process temperature, etc.
Q. Which chelating resins are available for boron removal, and how do they differ?

Chelating resins for boron removal are divided into two products by application:
CLR-B3 and CLR-B3UP. Both use a glucamine functional group and have high selectivity for boron, but their intended applications differ.
CLR-B3 is a general wastewater treatment product that selectively removes boron even in the presence of high concentrations of other anions, while CLR-B3UP has low TOC leaching (ΔTOC < 5 ppb) and is used as a boron polisher in ultrapure water production.
Q. Is there a chelating resin that selectively removes only mercury (Hg) from wastewater?

Yes, CLR-10 is a product specialized for mercury treatment. It uses a thiouronium functional group and has a high adsorption capacity for mercury, while its adsorption rate and capacity for other heavy metals are low, making it well suited to selective mercury treatment.
Q. Which product is suitable for selectively removing heavy metals such as chromium and nickel separately from alkali metals?

When you want to selectively separate only heavy metals such as chromium and nickel in the presence of large amounts of alkali metals such as sodium and alkaline earth metals such as calcium, CLR-20 is suitable. CLR-20 is a chelating resin with a polyamine functional group that has excellent selectivity for heavy metals but does not adsorb alkali metal ions (Na⁺, K⁺) or alkaline earth metal ions (Ca²⁺, Mg²⁺), so it is used in specialty applications to separate only the target heavy metals when these ions are also present.
