Abstract
The present invention provides a process for recovering a volatile acid charaterized by bringing a waste liquid containing the volatile acid into contact with an amine having a boiling point of at least 50.degree. C. to thereby cause the amine to tonically adsorb the acid from the waste liquid, and thereafter heating the amine to desorb the acid, and a process for treating waste water utilizing this process.
