Highly selective for heavy metal ions including Cu²⁺, Ni²⁺, Co²⁺, and Zn²⁺ under acidic to neutral pH conditions.
Stable iminodiacetic acid functional groups ensure excellent chemical and thermal resistance in industrial process streams.
Low swelling ratio and high mechanical strength enable reliable performance in packed-bed and continuous ion exchange systems.
Regenerable with dilute acid (e.g., 2–4% H₂SO₄ or HCl), supporting sustainable operation and reduced waste disposal costs.
Consistent bead uniformity and narrow particle size distribution (0.3–1.2 mm) optimize hydraulic flow and mass transfer efficiency.
Removal and recovery of copper from electroplating rinse waters and PCB manufacturing effluents.
Selective separation of nickel and cobalt from hydrometallurgical leach solutions in battery metal refining.
Purification of process streams in pharmaceutical synthesis where trace metal catalysts must be strictly controlled.
Treatment of mining wastewater to meet stringent discharge limits for heavy metals prior to environmental release.
Pre-concentration of target metals from low-concentration industrial wastewaters for subsequent electrowinning or precipitation.
