| Abstract: | Heavy metal pollution is one of the typical types of soil pollution.The main objective of the study is to analyse the passivation mechanism of granulated red mud to the heavy metals in soil and determine the best granulated red mud treatment in remediating soil contaminated with heavy metals that contribute to the growth of leeks.A treatment with granulated red mud addition was used to repair the soil which was polluted by Pb and Zn in incubation experiment.The concentration of heavy metals in soil(with and... |
