Specialty Resin
Platinum-Palladium Precious Metal Extraction Resin
Macroporous chelating catalysts, with thiourea/thiol/isothiourea as functional groups, exhibit high selectivity, high capacity, and acid and alkali resistance for Pt²⁺ / Pt⁴⁺ and Pd²⁺ / Pd⁴⁺ . They are widely used in hydrometallurgy, catalyst recovery, and electronic wastewater refining.
Applications Include
Automotive three-way catalyst recovery (selective adsorption of Pt/Pd/Rh in leachate ); electronic/electroplating wastewater (recovery of trace Pt and Pd (ppm→ppb level);hydrometallurgy (separation of copper-nickel ore anode slime and platinum group metal concentrates) ; chemical catalysts ( regeneration of spent catalysts such as Pd/C and Pt/ Al₂O₃ ) .
