Abstract
Abstract Own studies and literature data allowed for the evaluation of sorbents in view of the general verification criteria, which are necessary for any sorbent to be applied with no harm to the environment. Polymeric forms of Al13and Si compounds are examples of mineral sorbents that influence metals' toxicity in the environment.
Highlights
Gentle techniques for the remediation of toxic metal-contaminated soils aim at using immobilizing agents that influence soil fertility with no damage on its structure (Badora et al 1998; Badora 1999, 2002a,b)
Polymeric forms of Al13 and Si compounds are examples of mineral sorbents, whose influence on heavy metals' toxicity within the natural environment has been recognized in part (Ludwig 1990; Furrer 1993; Lothenbach et al 1997; Lothenbach et al 1998; Badora 2001a)
Other reports (Badora 1998a,b, 2002a,b) revealed that the addition of organic substance in the form of citric and humic acids had no significant effects on Cd and Zn immobilization by Al13, during experiments carried out under hydroponic conditions
Summary
Gentle techniques for the remediation of toxic metal-contaminated soils aim at using immobilizing agents that influence soil fertility with no damage on its structure (Badora et al 1998; Badora 1999, 2002a,b). Polymeric forms of Al13 and Si compounds are examples of mineral sorbents, whose influence on heavy metals' toxicity within the natural environment has been recognized in part (Ludwig 1990; Furrer 1993; Lothenbach et al 1997; Lothenbach et al 1998; Badora 2001a). Own studies (Badora et al 1998; Badora 1998a,b,c, 1999, 2001a,b, 2002a,b; Badora, Grenda 2000, 2002; Badora 2010, 2011) and literature data allowed for analyzing the above sorbents in view of the general verification criteria, which is necessary for the sorbents to be applied with no harm to the environment. The current paper deals with the evaluation of Al, Mn, and selected heavy metals' detoxication mechanisms by polymeric forms of Al13 and Si compounds based on literature references and own studies
