description A process based on ion exchange with separated beds is disclosed for the deionization of substances that are not stable in the presence of strongly acidic cation exchangers, wherein the solution to be deionized is contacted with a first bed consisting of a basic anion exchanger in the form of hydrogen carbonate and subsequently with a second bed, connected in series, consisting of a weakly acidic cation exchanger in hydrogen form.
