Abstract
A greater yield of chlorine dioxide from a chlorine dioxide generating process is obtained by providing acidic or acidity-generating components in the product chlorine dioxide solution to provide a chlorine dioxide solution having a pH below about 5.5.
Claims8
An aqueous solution of chlorine dioxide originating from a chlorine dioxide generating process having a purity with respect to chlorine dioxide of at least about 95% and acidified by the presence of at least one acidic or acidity-generating component to provide a pH of about 2.2 to about 3.9, wherein the chlorine dioxide generating process is hydrogen-peroxide based and chlorine and hydrogen peroxide present in the chlorine dioxide solution in a product storage tank react to form hydrochloric acid, which is the acidic or acidic-forming component, and wherein the aqueous chlorine dioxide solution is rendered substantially free from hydrogen peroxide.
