Highly selective catalytic functionality for targeted ion exchange and redox-assisted reactions.
Exceptional chemical stability in acidic, alkaline, and oxidizing environments (pH 1–14).
Thermally robust up to 120 °C with minimal functional group leaching under continuous operation.
Uniform spherical bead morphology ensuring low pressure drop and consistent flow distribution.
Regenerable using standard reagents (e.g., dilute HCl, NaOH), supporting sustainable process cycles.
Heavy metal recovery and speciation control in hydrometallurgical leach solutions.
Catalytic denitrification of industrial wastewater via coupled ion exchange–redox pathways.
Pretreatment of ultrapure water systems to remove trace transition metals and catalytic impurities.
Selective separation of rare earth elements (REEs) from complex mixed feedstocks.
Stabilization and removal of reactive anions (e.g., arsenate, selenate) in mining effluents.
