Beschreibung
Zusammenfassung:	La présente invention porte sur un procédé d'inertage de matériau d'excavation en vue de leur analyse. A process for rendering excavation material inert for the purpose of their analysis, of their storage and/or of their valorisation. The process for inerting the excavation material includes adding an organic acid, of a complexing agent or of a diaminotetracarboxylic acid to the excavation material, the complexing agent being chosen from a sugar alcohol, a cationic surface-active agent and their mixtures. Also, a method of determining the concentration by weight of a polluting inorganic element included in an excavated material, a method of storage of the inert excavation material, and a method of valorising the inerted material.
