METHOD OF SCAVENGING OXYGEN IN AQUEOUS SYSTEMS

摘要

An improved oxygen scavenger for aqueous mediums is disclosed which is a hydroxylamine in combination with a water soluble salt of manganese or vanadium, or esters of gallic acid. The addition of the water soluble salts of manganese or vanadium, or esters of gallic acid catalyzes the oxygen removal activity of the hydroxylamine. The combination of the present invention is particularly effective in industrial water systems such as boilers water or cooling water systems.
