【発明の名称】規定されたh/d比を有する吸着床でのイオン交換による超高純度過酸化水素溶液の調製プロセス

Document Type and Number:

Japanese Patent JP2002500610

Kind Code:

A

Abstract:

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.
