An experimental study of the quantitative assessment of Cr（Ⅵ） reducibility using δ53 Cr

"In-situ remediation"of contaminated groundwater is a most prosprective technology in the world today,but there is not a scientific and effective method to estimate the technology of"In-situ remediation"of Cr-contaminated groundwater.Quantitative evaluation of Cr(Ⅵ) reducibility becomes a key problem of protection and restoration for groundwater pollution by chromium.Typical experiments of Cr(Ⅵ) reduction were conducted to analyze the changing disciplinarian of Cr(Ⅵ) stable isotopes during the r...
