Zusammenfassung |
AB |
[EN] The invention is a method for removing dissolved oxygen from alkaline water which comprises adding to alkaline water containing dissolved oxygen an effective oxygen-scavenging amount of a water-soluble carboxylate at temperatures above 400 DEG F. A preferred material is tartronic acid. At lower temperatures, a catalyst is also required. |
