Cement-based solidification/stabilization (S/S) technology is often used to remediate
chromium (Cr) contaminated soils. The valence state and mobility of Cr in soils are closely …

Ferrihydrites were prepared by coprecipitation (COP) or adsorption (ADS) of arsenate, and
the products were characterized using solid-state methods. In addition, the kinetics of …

Arsenic, a common highly-toxic pollutant, is mainly associated with the hydrous ferric oxides
in soils and minerals. A possible mechanism for arsenic mobilization is the reductive …
