Applications

Designed for the selective extraction of heavy metal cations from weakly acidic to weakly basic solutions. Suitable for:

• Selective removal of metal contaminants from processing baths.
• Concentration, extraction, and recovery of heavy metals from hydrometallurgical solutions.
• Recovery of useful metals from electroplating rinse waters.
• Selective trace removal of heavy metals from industrial metal surface finishing effluents, even in the presence of high calcium concentrations.
• Selective removal of heavy metals from contaminated ground and wastewater streams for potable water production and groundwater remediation.

The resin exhibits selective extraction of heavy metal cations in the presence of complexing agents such as nitrogen compounds, multivalent carboxylic acids, and phosphates.
