Trace Gold, Silver, and Palladium Adsorption Analysis and Extraction System.

Acidic colloidal palladium waste liquid is produced from the activation treatment of the inner walls of through-holes on circuit boards. The formulation consists of a weak hydrochloric acid bath with added NaCl (salt) stabilizer. Since palladium is wrapped by tin (Sn), it is necessary to break the tin encapsulation in order to adsorb palladium. Ordinary resins and activated carbon are almost unable to adsorb palladium, or their effect is very poor. Our company has specially developed and produced activated carbon for colloidal palladium adsorption, which can effectively recover colloidal palladium waste liquid. The adsorption capacity can reach 5-20 g/L.
Also applicable to ionic palladium.
