Ion Exchange Resins for Metal Recovery & Wastewater Treatment

Samyang's TRILITE® ion exchange resins for metal recovery and wastewater treatment use chelating resins matched to the target metal to selectively remove or recover metal ions from wastewater.

Key Features

TRILITE® ion exchange resins and chelating resins can be used to remove,
separate, and concentrate various metal ions.

In heavy metal wastewater treatment in particular, target metal ions such as chromium (Cr), copper (Cu), and nickel (Ni) can be selectively removed. In mining, plating, metal refining, and the electronics industry, specific metal ions can also be selectively separated and concentrated to recover valuable metal resources.

Metal Recovery (Hydrometallurgy)

· Recovery of gold from gold mines or gold-plating wastewater
· Recovery of uranium from uranium ore
· Recovery of rhodium from rhodium-plating wastewater
· Recovery of platinum and palladium from spent catalyst leachate
Wastewater Treatment

· Industrial wastewater treatment : Removal of metal ions such as chromium (Cr), copper (Cu), and nickel (Ni) using chelating resins and ion exchange resins
· Plating wastewater treatment : Treatment of chromium- and cyanide-containing wastewater from plating processes
· Painting process treatment : Purification of electrodeposition paint from painting processes
· Specific ion removal: Selective removal of specific ions such as mercury, boron, fluoride, and nitrate
· Wastewater reuse : Removal of specific ions from effluent to produce water quality suitable for reuse

FAQ

Q. Can Samyang's TRILITE® ion exchange resins also remove nitrate nitrogen from wastewater?
Yes. Samyang's TRILITE® CLR-N is a triethylamine-type chelating resin specialized for nitrate removal. It selectively removes nitrate even in the presence of high concentrations of sulfate or other multivalent ions, and is better suited to nitrate removal than conventional anion exchange resins. With a specially reinforced matrix structure providing high exchange capacity and physicochemical stability, it is used to remove nitrate from water.
- Total exchange capacity: ≥ 0.8 eq/L
- Uniformity coefficient: ≤ 1.6
- Moisture content: 48–58%
Q. Can Samyang's TRILITE® ion exchange resins selectively remove only specific ions such as mercury, boron, and fluoride from wastewater?

Yes. Samyang's TRILITE® ion exchange resins and chelating resins are designed to selectively remove specific ions such as mercury, boron, fluoride, and nitrate. Their high binding selectivity for the target ion, even when other ions coexist at high concentrations, allows precise removal of trace or specific ions that are difficult to separate by chemical coagulation and precipitation.
Q. What are the benefits of applying chelating resins to wastewater treatment?

Chelating resins are characterized by their ability to remove difficult-to-treat heavy metals selectively and economically.

They can selectively separate only the target metal even when multiple metals are present; however, because ion exchange resins, including chelating resins, are vulnerable to the inflow of organic matter and similar contaminants, appropriate pre-treatment (neutralization, coagulation, sand filtration, activated carbon, etc.) is essential.
