Highly selective for nitrate (NO₃⁻) and perchlorate (ClO₄⁻) removal from water.
Functionalized with tertiary amine groups on a macroporous polystyrene-divinylbenzene matrix.
Exceptional physical and chemical stability under repeated regeneration cycles.
Low pressure drop and high flow rate capability due to uniform spherical bead morphology.
Regenerable with sodium chloride (NaCl), enabling cost-effective, closed-loop operation.
Drinking water treatment for nitrate and perchlorate compliance.
Groundwater remediation at contaminated industrial or military sites.
Pre-treatment for reverse osmosis systems to protect membranes from oxidant-sensitive anions.
Municipal water utility polishing applications targeting emerging contaminants.
