Procedure

The present invention comprises the use of ammonium zinc sulfate hydrate to selectively recover ammonia from an aqueous solution in a solid crystalline form. The water and ammonia may then be recovered by heating the crystals and recovering the water and ammonia in the off gases. This process would then leave behind zinc sulfate and sulfuric acid, which can be resolubilized and recycled.
