Product Overview

• Precious Metal Recovery (Cl⁻ type): Recovery of cyano/chlorine complexes such as gold, silver, platinum, palladium, rhodium, and iridium from wastewater/process solutions.

• Removal/recovery of anionic heavy metal complexes (e.g., AuCl₄⁻, PtCl₆²⁻) from hydrochloric acid systems.

• Uranium Extraction (Cl⁻ type): Recovery of uranium (UO₂(CO₃)₂²⁻, UO₂(SO₄)₂²⁻) from carbonate/sulfuric acid leaching solutions.

• Petrochemicals (OH⁻ type): Removal of mercaptan sulfur (RS⁻) from hydrocarbon streams, reducing corrosion and odor.

• Organic catalysis (OH⁻ type): Catalyzes small polar organic reactions (such as condensation and addition) at 30–60℃, with high selectivity and easy separation. Uniform particle size (monodisperse): Uniformity coefficient ≤1.1, extremely low pressure drop, uniform packing, and excellent kinetic performance, suitable for precision separation and continuous flow processes.

• Strong basic exchange capacity: Type I strong basic functional groups, efficiently removes anions (such as metal complexes, sulfate, and chloride ions) across the entire pH range.

• Chemical stability: Resistant to dilute acids, dilute alkalis, salt solutions, and organic solvents.

• Resistant to low concentrations of oxidants, with long-term cycling stability.
