the resin process is to recover palladium from waste catalysts, waste electrical components, damaged containers containing palladium and waste electroplating solution by chelating resin. It has the advantages of high separation efficiency, simple operation and recyclable resin. the palladium extraction resin produced by Jiangsu Jinshan New Materials Co., Ltd. Has high selective affinity and adsorption rate, and is easy to regenerate and has high regeneration rate, so it is widely used in industrial palladium metal recovery.
