Abstract

La presente invención se refiere al uso de una composición que comprende al menos un agente neutralizante ácido-base para descontaminar una atmósfera contaminada por un gas corrosivo, dicho agente neutralizante ácido-base tiene al menos 2 pKa y se caracteriza en que: - pKa1 ≤ pKa 2 - pKa 1>2 - pKa 2<12 - 4< ½ (pKa 1 +pKa 2) < 10 siendo pKa 1 el pKa básico más pequeño y pKa 2 representa el pKa ácido más grande. La presente invención también se refiere a un método de descontaminación de una atmósfera contaminada por un gas corrosivo que comprende la pulverización de dicho agente neutralizante, y a un dispositivo de descontaminación.
