Recovery of iodide from chemical process wastewater |
| abstract |
The recovery of iodide from chemical process wastewater is accomplished by loading the wastewater containing iodide onto a strongly basic anion-exchange resin in free-base form; eluting the sorbed iodide from the resin with aqueous strong acid (e.g., hydrochloric acid); loading the iodide-rich cuts onto a weakly basic anion-exchange resin in free-base form; and eluting the sorbed iodide with aqueous base (e.g., sodium hydroxide). The recovered iodide typically has sufficient purity to permit its re-use in the chemical process. |
