Abstract
The degradation of an absorbent solution comprising organic compounds with an amine functional group in aqueous solution is substantially reduced in the presence of a small amount of degradation inhibiting agents belonging to the family of derivatives of triazoles or of a tetrazole at least one substituent of which contains a sulfur atom. The absorbent solution is used to deacidize a gaseous effluent.
