In this study, soil washing is applied for the remediation of heavy-metal (Pb, Cu and Zn) contaminated paddy soil located near an abandoned mine area. FeCl3 washing solutions were used in bench-scale soil washing experiments at concentrations in the range of 0.1 to 1M. The strong acid, HCl was also used in this study for comparison. The washing process was performed at room temperature, mixing at 200 RPM for 1h and a liquid to solid ratio of 2. A sequential extraction technique was performed to evaluate the chemical fractions of Pb in the soils. The soil washing effectiveness was evaluated and compared against regulations applicable to residential districts (Korean warning standards). The soil washing results showed that the heavy metal concentrations were reduced with increasing concentrations of FeCl3. Moreover, the lowest heavy metal concentrations were obtained with a 1M FeCl3 washing solution. In the case of Pb removal, a 0.3M FeCl3 washing solution was required to comply with the Korean warning standard of 200mg/kg. The lowest Pb concentration of 117mg/kg was obtained with 1M FeCl3. Similar washing results were also obtained with HCl. The initial total concentrations for Cu and Zn were below the Korean warning standards of 150 and 300mg/kg, respectively. Consequently, the reduction in Cu and Zn from the contaminated paddy soil using FeCl3 washing solutions was rather limited. The sequential extraction results showed that the exchangeable and weak acid-soluble fractions of Pb were significantly reduced upon FeCl3 washing.
