  • Iodine recovery process
    Patent number: 4131645
    Abstract: Iodine is recovered from an aqueous solution containing iodide such as underground brine by repeated cycles of (1) passing the brine through a basic anion exchange resin to adsorb iodide, and (2) oxidizing adsorbed iodide to iodine by passing an acidified aqueous iodate solution (e.g., NaIO.sub.3) through the resin. The cycle is repeated many times until the resin is iodine-loaded. Iodine is then eluted from the resin, for example, with aqueous NaOH and recovered from the eluate by conventional means.
