Specialty Ion Exchange Resin for Precious Metallic Palladium(Pd) Extraction/Recycle


KP-2011Pd is an ion exchange resin synthesized with special technology, specializing in removing strong-acid complexes of precious metals. For its highly firm and solid structure, this resin performs with its high anti-osmotic efficiency and excellent mechanical &shock resistance as well as functions anti-pollution from organics. 

Owing to its special strong-base functional groups and fine granularity, KP-2011Pd performs well in complete exchange capacity and strong stability, as the optimal electronic-grade product model that is most applicable in pure water systems of electroplating hydrometallurgy process or semiconductor production, where merely traces of strong-acid radicals remain. Considering the increasing order of affinity that its special functional groups avail to, KP-2011Pd is designed in priority of removing strong-acid anions-palladium complexes with rather high exchange capacity, which is being widely applied in pure water systems of hydrometallurgy and electroplating process, followed by palladium extraction, enrichment or recovery in general.
