Process for the preparation of an ultra pure solution of hydrogen peroxide by ion exchange with recycling |
摘要 |
Provided is a process for the preparation of an ultrapure hydrogen peroxide solution. The process comprises at least one sequence which includes passing a solution to be purified successively through at least one bed of anion-exchange adsorbents (AEA) and at least one bed of cation-exchange adsorbents (CEA). A non-zero proportion of the solution exiting from one of the beds is recycled to a point upstream of the one bed or upstream of a preceding bed or upstream of the first bed of the first of the at least one sequence. Also provided is a plant for the implementation of the inventive process.
