| abstract |
The present invention relates to the use of a composition comprising at least one acid-base neutralising agent in order to decontaminate an atmosphere contaminated by a corrosive gas, the acid-base neutralising agent having a pKa of at least 2 and being characterised in that: - pKa1 ≤ pKa2 - pKa1 > 2 - pKa2 < 12 - 4 < ½(pKa1 + pKa2) < 10, pKa1 representing the lowest base pKa and pKa2 representing the highest acid pKa. The present invention also relates to a method for decontaminating an atmosphere contaminated by a corrosive gas, which method comprises spraying the neutralising agent, and to a decontamination device. |
