This disclosure describes systems, methods, and apparatus for recovery and purification of iodine from strong brine solutions having low concentrations of iodine. This can involve acidifying and oxidizing the strong brine solution to produce a solution of processed brine and elemental iodine. This solution can then be passed through a countercurrent sorber causing the elemental idodine to adsorb onto a solid sorbent such as GAC. The iodine-loaded sorbent is separated and regenerated, for instance via heating, producing regenerated sorbent and iodine vapor. The vapor can be condensed thus leaving solid elemental iodine. |
