Abstract

In batch, column and lysimeter experiments the addition of HCl or FeCl3 to a soil heavily polluted with lead markedly reduced the soil pH and resulted in the dissolution of lead. The amount of lead dissolved from the soil was strongly correlated with the pH of the system: at pH 2.5, 45-65% of the total lead in the soil was extracted in batch experiments. In the lysimeter experiment 77% and 66% of the total lead was displaced from the 0-10 cm soil layer by HCl and FeCl3, respectively. The displaced lead was fixed in the 10-30 cm soil layer. No lead was detected in the effluent. (Abstract retrieved from CAB Abstracts by CABI’s permission)
