The present invention generally provides sulfide scavenger solutions and process es that have high sulfide scavenging capacity, provide a reduction or elimination o f solids formation and avoid the use of chemicals that pose environmental concerns. The i nvention utilizes a dialdehyde, preferably ethanedial, for the purpose of reacting with a mines, amine carbonates, or other derivatives of amines that are liberated when certain scave nger solutions react with sulfides, including hydrogen sulfide and mercaptans. The scavenger so lutions that have been discovered to liberate amines are those formed by a reaction between a n amine and an aldehyde.
