Highly selective chelating resin with iminodiacetate functional groups for preferential binding of heavy metal cations.
Excellent chemical and physical stability across broad pH range (1–12), enabling robust performance in aggressive process streams.
Fast kinetics and high exchange capacity for transition metals including Cu²⁺, Ni²⁺, Zn²⁺, and Co²⁺.
Low pressure drop and uniform spherical bead structure ensure consistent hydraulic performance in fixed-bed and moving-bed systems.
Regenerable with dilute acid solutions (e.g., 5% H₂SO₄ or HCl), supporting sustainable closed-loop operation.
Heavy metal removal from industrial wastewater in electroplating and metal finishing facilities.
Recovery of valuable metals (e.g., copper, nickel) from leachates in hydrometallurgical processes.
Pretreatment of feed water for boiler systems to prevent heavy metal-induced corrosion and scaling.
Polishing step in semiconductor-grade ultrapure water (UPW) production to meet stringent trace metal specifications.
Decolorization and metal ion scavenging in pharmaceutical and fine chemical synthesis effluents.
