Abstract (en)
[origin: WO2009022237A2] A process for the removal and recovery of at least one heavy metal and at least one halogen from a liquid stream in a chemical process is disclosed. The process comprises the steps of contacting the liquid stream with a strong base anion exchange resin; and contacting a discharge stream from the first step with a chelating cation exchange resin. The recovery process optionally includes a step regenerating the anion exchange resin by contacting the anion exchange resin with an anion exchange resin regeneration solution to form recovered heavy metals and halogens. Optimally, the recovery process of the present invention also includes a step of regenerating the chelating cation exchange resin to form recovered heavy metals and halogens.
