METHOD FOR PREPARING AN ULTRAPURE HYDROGEN PEROXIDE SOLUTION BY ION EXCHANGE IN THE PRESENCE OF ION ACETATE

摘要

The invention concerns a method for preparing an ultrapure hydrogen peroxide solution, characterised in that it comprises at least asequence which involves passing the solution to be purified, on at least a bed of anion-exchanging adsorbents (AEA) and at least a bed ofcation-exchanging adsorbents (AEC) and at least one anion-exchanging adsorbent bed contains carboxylate ions of formula R-COO- and,particularly, acetate ions. The invention also concerns an installation for implementing the method.
