A method for inhibiting formation of hexavalent chromium during oxidative remediation of a contaminated site containing trivalent chromium is described. The method comprises introducing (103, 106) ozone at a first point to the contaminated site, where the ozone is introduced at a first frequency and for a first period of time, and introducing hydrogen peroxide to the contaminated site, where the hydrogen peroxide is introduced at a second frequency and for a second period of time. The first and second frequencies and first and second periods of time are selected to inhibit formation of hexavalent chromium within the site of remediation.
L'invention concerne l'inhibition de la formation de chrome hexavalent pendant la restauration oxydante d'un site contaminé contenant du chrome trivalent. Le procédé comprend l'introduction d'ozone à un premier point sur le site contaminé, l'ozone étant introduit à une première fréquence et pendant une première période de temps, et l'introduction de peroxyde d'hydrogène sur le site contaminé, le peroxyde d'hydrogène étant introduit à une seconde fréquence et pendant une seconde période de temps. Les première et seconde fréquences et les première et seconde périodes de temps sont choisis pour inhiber la formation de chrome hexavalent à l'intérieur du site de restauration.
