Immobilization of Zn, Cu, and Pb in contaminated soils

bilization of other metals (e.g., Cu, Zn, and Cd) [5,1517]. A single amendment may not be suitable for multiple metals and the treatment effectiveness depends on assessment methods [1820].For example, addition of P to a soil contaminated with Pb, Zn, and Cd reduced the bioavailable Pb, but increased plant Cd concentrations [19].

Heavy metals (Cd, Pb, Zn, Ni, Cu and Cr(III)) removal from

Experiment on the use of sand, calcite and clay for Pb 2+, Zn 2+ and Cu 2+ sorption in the presence of humid acids had found that, at higher pH levels, heavy metals are removed from solution by coprecipitation with calcite or by sorption on Fe or Mn oxides that are precipitated on carbonate particles (Petrovic et al., 1999).

Determination of Mn, Fe, Ni, Cu, Zn, Cd and Pb in seawater

The collision/reaction cell was pressurized with O 2 gas for the analysis of Mn, Ni, Cu, Cd and Pb and H 2 gas for the analysis of Fe and Zn, which removed common interferences (e.g. ArO + on 56 Fe and MoO + on Cd) yet maintained the highest instrument sensitivity across

The downstream concentrations for Cu, Pb, Sn, and Zn were nearly the same as the corresponding their upstream values. Concentrations of Cu, Pb, Sn, and Zn tended to decrease as the distance from e waste processing area away in downstream (see Fig. 6 for detail). These concentration trends of Cu, Pb, Sn, and Zn were similar to those of EW soils

Stabilization of As, Cr, Cu, Pb and Zn in soil using

Cu and Zn (Hartley et al., 2004). Warren et al., 2003, Warren and Alloway, 2003 observed increased plant uptake of other contaminants including Cu, Zn and Pb in soil amended with Fe(II) sulfate and lime. The authors explained that there was an insufficient amount of lime added and suggested a ratio of lime/Fe oxide necessary for maintaining
