Remediation of heavy metal contaminated soil washing residues with amino polycarboxylic acids

Environmental Remediation Technologies for Metal-Contaminated Soils

“…The performance of NTA, EDDS and EDTA for the extraction of Cd, Cu, Pb, and Zn from soils by Polettini et al (2006) and, among the biodegradable options, EDDS performed superior than the NTA. The removal of Cu, Pb, and Zn by the action of the EDDS and MGDA has been reported by Arwidsson et al (2010). The removal of Cu, Pb, and Zn by the action of the EDDS and MGDA has been reported by Arwidsson et al (2010).…”

Phytoremediation

“…Water application may be via surface fl ooding, a system of sprinklers, or vertical and horizontal drains. Various reagents may be added to fl ushing water to support Cu solubilization: diluted mineral acids (HCl or HNO 3 ), organic acids that act additionally as complexing agents (citric acid, acetic acid) or chelating agents such as EDTA, NTA, or glycine (Fischer et al 1992 ;Lim et al 2004 ;Dermont et al 2008 ;Leštan et al 2008 ;Zou et al 2009 ;Arwidsson et al 2010 ). The effi ciency of extraction depends highly on soil permeability.…”
