Abstract
Treatment process for concentrated acids, characterized in that the treatment process for concentrated acids such as nitric, sulfuric, hydrofluoric, chromic or other acids, alone or in mixtures, consists of adding these PO4 ion acids, and possibly of a stable acid-active agent in the concentrated acid, in order to allow the metals to remain in contact with these acids for a long time, without suffering corrosion.
