Zusammenfassung:	The present invention relates to reduction of corrosion. The present invention includes a method of decreasing corrosion during ammonia extraction. The method includes performing a process to extract ammonia using ammonia extraction equipment. The ammonia extraction equipment includes an ammonia absorber, an ammonia desorber, and an aqueous solution. The aqueous solution includes an acid or an ammonium salt thereof. The method also includes sparging an oxygen-containing gas into the solution in the ammonia absorber, the ammonia desorber, or therebetween. The invention also provides a system that can perform the method.
