Highly selective chelating resin specifically engineered for the removal of heavy metal cations (e.g., Cu²⁺, Ni²⁺, Zn²⁺, Cd²⁺, Pb²⁺) from low-concentration industrial effluents.
Stable iminodiacetate functional group grafted onto a macroporous polystyrene-divinylbenzene matrix, ensuring excellent chemical and physical durability across wide pH and oxidative conditions.
Superior kinetic performance and high total capacity (>2.0 eq/L in Na⁺ form) with strong affinity even at trace metal concentrations (<1 ppm) and in the presence of competing calcium and magnesium ions.
Low pressure drop and high bed stability due to uniform spherical bead morphology (0.3–1.2 mm particle size) and high mechanical strength, minimizing attrition during hydraulic cycling.
Regenerable with dilute acid (e.g., 5% H₂SO₄ or HCl), enabling cost-effective closed-loop operation and minimal waste generation.
Electroplating and metal finishing wastewater treatment for compliance with stringent discharge limits on heavy metals.
Leachate polishing in mining and hydrometallurgical operations to recover valuable metals and meet environmental regulations.
Electronic manufacturing wastewater treatment, particularly for copper removal from etching and cleaning rinse streams.
Pharmaceutical and fine chemical process water purification where ultra-low heavy metal contamination is critical.
Pre-treatment of feedwater for reverse osmosis systems to prevent heavy metal fouling of membranes.
