METHOD OF TREATING AQUEOUS SOLUTIONS WITH A WEAKLY ACIDIC CATION AND BASIC ANION EXCHANGE RESINS

摘要

A method for treating aqueous solutions by ion exchange uses a weakly acidic cation exchange resin and a strongly basic anion exchange resin to remove corrosion products and metal ion leakage from a solution while substantially reducing the quantity of acid required to regenerate the cation exchange resin. Substantial quantities of ammonia and other volatile amines are not removed from the solution during the treatment process.
