A method for treating a surface to decontaminate the surface by chemically altering contaminants on the surface. The method comprises applying to the surface particles of a zero valent metal capable of reacting with oxygen and water to form hydroxyl radicals, and exposing the particles to oxygen and water. The method may be carried out in the presence of air.

L'invention concerne un procédé de traitement de surface permettant de décontaminer une surface en modifiant chimiquement les contaminants situés sur la surface. Ce procédé consiste à appliquer sur la surface des particules d'un métal à valence zéro capable de réagir avec de l'oxygène et de l'eau pour former des radicaux hydroxyle, puis à exposer les particules à de l'oxygène et à de l'eau. Ce procédé peut être mis en oeuvre en présence d'air.
