Abstract
Official abstract text for this publication.
A process for generating aqueous chlorine dioxide solutions includes adding a solid phase alkali metal chlorite, a solid phase acid, and a solid phase oxidizing agent to an aqueous solution, wherein the solid phase acid ahs a pKa less than 4. Also disclosed are compositions for producing chlorine dioxide solutions.
First claim
Opening claim text (preview).
What is claimed is: 1. A batch process for generating an aqueous solution of chlorine dioxide, the process consisting of: adding a composition consisting of a solid phase oxidizer to an aqueous solution consisting of water and sodium chlorite; agitating the aqueous solution; and generating chlorine dioxide in the aqueous solution, wherein the solid phase oxidizer is selected from the group consisting of 1,3-dichloro-5,5-dimethylhydantoin and for twenty four hours. 2. The process of claim 1 , wherein the aqueous solution is at 16° C.
