  • Adsorption of Heavy Metal Pollutants by Landfill Soils

    a general order of Pb = Cu > Ni = Cd > Zn was concluded. The removal of heavy metals by the seven tested soils is rep­ resented by Taichung sanitary landfill red loam soil (R) and is shown in Figure 2. Such a removal sequence as a function of pH might have something to do with the solubility product constants of heavy metal hydroxides.

    In comparison the biodegradable chelating agent chitosan (pH 3.3) performed even better than EDTA (pH 3.1) at 2.0 g L −1 to extract Cu and Ni from a pH 5.0 clay loam (Jiang et al. 2011). The removal efficiency was the highest for Pb (75 ) and the lowest for Cu (25 ).

  • Spatial distribution of metals in soils under agriculture

    Cr Cu Pb and Zn were associated with residual fraction Mn was mostly bound to Fe/Mn oxides and carbonates fractions while Cd was associated mainly carbonate fractions. Similar study ( Banat et al. 2007 ) showed that the chemical fractionation of some metals (Cd As and Pb) in soils north of Jordan Valley were mainly in the residual fraction.
