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.

Abstract: The invention is for a process of removing acid salt contaminants from a resin solution. The process comprises providing an organic solution of a phenolic resin having a portion of its phenolic hydroxyl groups condensed with an acid halide in the presence of a base catalyst. The organic solutions is then contacted with a strong acid cation exchange resin and a base anion exchange resin for a time sufficient to remove essentially all of said acid salt contaminants. Acid salt contamination is reduced to a level below normal detection limits.

Abstract: In an ion exchanger having a single upright tank with upper and lower stratified beds of resins respectively adapted to absorbing different ions (cations or anions) of the same ionic polarity, a distributor for the inflow of water into the tank is disposed substantially at the interface between the two beds and used to effect the upward backwashing of the upper bed alone and, during regeneration of weak-and-strong-type exchange resins by the same regenerant passed successively through the beds of strong-andweak-type resins, to dilute the regenerant to the concentration best suited for regeneration of the weak-type resin.
