- Аннотация: Reduction of Cd, Cu, Ni, and Pb Mobility by Active Si in a Laboratory Study. Abstract: Soluble forms of Si and Si-rich substances may reduce both metal mobility and toxicity. A series of column experiments were performed to investigate the influence of Si-rich materials on the mobility and leaching potential of certain metals. Column experiments were conducted using sandy soil that had been treated with various forms of a Si-rich substance, i.e. diatomaceous earth, zeolite, amorphous silicon dioxide, and concentrated monosilicic acid. The soil was also treated with soluble forms of Cd, Cu, Ni, and Pb to simulate a contaminated mine site. Application of the Si-rich materials resulted in metal immobilization and reduced leaching. It appears that monosilicic acid can cause both physical adsorption and metal precipitation within contaminated soils. Further investigations are recommended to assess the potential use of this approach for remediation of mine tailings and decontamination mine sites. Keywords: Cadmium Copper Nickel Lead Metal mobility, Monosilicic acid.
