Remediation-By-Reduction Strategies for Chromate-Contaminated Soils

The reduction of Chromium (VI) to Chromium (III) is considered an acceptable clean-up strategy which does not change the Cr content of the soil. This reduction must produce inert forms of Cr(III), must not generate undesirable reaction products as a result of oxidation of the reduction agent, and mu...

Description
Summary:The reduction of Chromium (VI) to Chromium (III) is considered an acceptable clean-up strategy which does not change the Cr content of the soil. This reduction must produce inert forms of Cr(III), must not generate undesirable reaction products as a result of oxidation of the reduction agent, and must prevent notable changes in soil pH and Eh. A water extraction method is combined with an alkaline extraction method to separate insoluble forms of CR (IV) throughout the treatment. Reducing agents may include concentrations of C, Fe, and S as electron sources.
