Abstract
A process for the generation of chlorine dioxide from an alkali metal chlorate is provided that employs a waste sulphuric acid containing oxidizable organic material. Alkylation waste sulphuric acid from petroleum refining is particularly useful in this process. Conventional chlorate reducing agents used in the generation of chlorine dioxide can be partially or completely replaced by the organic material contained in the alkylation waste acid.
