CONTROLLING THE FORMATION OF HEXAVALENT CHROMIUM DURING AN OXIDATIVE REMEDIATION OF A CONTAMINATED SITE |
摘要 |
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. |
