ABSTRACT OF THE DISCLOSURE An improved method for scavenging dissolved oxygen from alkaline waters with either erythorbic acid or ascorbic acid is described. The acid is used combined with either magnesium ion or copper ion as catalysts, or in the presence of a pH control agent which maintains the pH above 7. By this means the known oxygen scavenging properties of these acids are substantially improved.
