Abstract

Chlorine dioxide is generated from a sulfate free aqueous acid reaction medium using nitric acid as the acid source. Highly efficient chlorine dioxide generation at high production rate is achieved in the low acidity range below about 2 N at low concentrations of chlorate below about 3 M, under crystallizing and non-crystallizing conditions.
