%X Effects of red mud addition on the fractionation and bio-accessibility of Pb and Zn in soil were studied by batch soil column incubation experiment. The results showed that all treatments with red mud addition could significantly decrease the concentrations of HOAc-soluble Pb and Zn. Compared with the control, the treatment with 5% red mud addition could significantly decrease the concentrations of HOAc soluble Pb and Zn after 1, 2 and 3 months incubation (62.5%, 65.3% and 73.5% decrease, 56.7%, 65.8% and 67.4% decrease, for Pb and Zn, respectively). After 3 months incubation, the treatment with 1% red mud addition significantly decreased the concentration of bio-accessible Pb, however, all treatments including 1%, 2% and 5% red mud addition, significantly decreased the concentration of bio-accessible Zn. The results highlighted the potential of red mud amendments to reduce Pb and Zn bioavailability in contaminated soil.
