Chemical stabilization of metals/metalloids in contaminated soils

Research at Czech University of Life Sciences Prague

Chemical stabilization is a soil remediation method based on the application of various inorganic and organic amendments to contaminated soils. These stabilizing agents lower the mobility and bioavailability of risk elements in such soils. Immobilization is achieved through several physico-chemical processes, such as adsorption, complexation, precipitation and co-precipitation. Our research team studies sorption mechanisms on various amendments, mostly iron and manganese (nano-)oxides and biochar. The efficiency of the stabilizing agents is evaluated using batch, column and lysimeter experiments in the laboratory and field and modeled using geochemical and hydropedological transport models.
