Abstract

La présente invention porte sur l’utilisation d’une composition comprenant au moins un agent neutralisant acido-basique pour décontaminer une atmosphère contaminée par un gaz corrosif, ledit agent neutralisant acido-basique présentant au moins 2 pKa et étant caractérisé en ce que:- pKa1 ≤ pKa 2- pKa 1>2- pKa 2<12- 4< ½ (pKa 1 +pKa 2) < 10pKa 1 représentant le plus petit des pKa basiques et pKa 2 représentant le plus grand des pKa acides.La présente invention porte également sur un procédé de décontamination d’une atmosphère contaminée par un gaz corrosif comprenant la pulvérisation dudit agent neutralisant, et sur un dispositif de décontamination.Pas de figure.
