Method for preparing an ultrapure hydrogen peroxide solution by ion exchange with an anionic-cationic-anionic-cationic sequence

摘要

Provided is a process for the preparation of an ultrapure hydrogen peroxide solution. The process comprises at least one sequence which includes successively passing a solution to be purified through at least two beds of cation-exchange adsorbents (CEA) and two beds of anion-exchange adsorbents (AEA) according to the sequence:Also provided is a plant for the implementation of the inventive process.
