Abstract
We investigated the processes of zinc regeneration of carboxylic ion exchangers FIBAN by the solutions of sulfuric acid and sodium sulfate. It is shown that the mode of direct-flow continuous elution of the ion exchanger by the regeneration solution is not promising enough. It is planned to carry out regeneration by the solution of sulfuric acid circulating through a sorbent layer. For preparation of the ion exchanger for a new cycle of sorption it is recommended to treat the material with a mixed solution of sodium hydroxide and sodium sulfate.
