| description abstract | An acidic soil was deliberately contaminated with lead (Pb), cadmium (Cd), and chromium (Cr). The heavy metal speciation in the aged soil sample was analyzed using a sequential extraction procedure. A single-step extraction procedure was then employed to remove the heavy metals from the soil using sodium ethylenediaminetetraacetic acid, sodium nitrilotriacetic acid, and calcium trisodium diethylenetriaminepentaacetic acid. The extraction parameters were the type and concentration of chelating agent and the duration of extraction time. All the extractions that involved chelating agents were carried out at pH 7.0. The heavy metal extraction efficiencies of chelating agents were compared to those of | |
