Process for the preparation of an ultra pure hydrogen peroxide solution by ionic exchange in beds having defined H/D ratios

Provided is a process for the preparation of an ultrapure hydrogen peroxide solution. The process includes at least one sequence which includes successively passing a solution to be purified through at least one bed of cation-exchange adsorbents (CEA) and at least one bed of anion-exchange adsorbent...

More Information
Summary:Provided is a process for the preparation of an ultrapure hydrogen peroxide solution. The process includes at least one sequence which includes successively passing a solution to be purified through at least one bed of cation-exchange adsorbents (CEA) and at least one bed of anion-exchange adsorbents (AEA). The beds of adsorbents each exhibit a height to diameter ratio of greater than 3. Also provided is a plant for the implementation of the inventive process.
