- In this paper, the effects of EDTA and EDDS as chelating agents, chelating-induced maize remediation on Tl-contaminated soils and their heavy metal leakage characteristics under rainfall conditions were studied. The results showed that both EDTA and EDDS could promote the uptake of Tl by maize, and EDDS could further promote the transfer of Tl from maize roots to shoot, and the effect of EDTA was weaker; The content of Tl in the leachate during the leaching process obeys the linear decrease rule with increasing rainfall .Under the condition of acid rain, the concentration of Tl was higher than that of non-acid rain in the leachate of EDDS chelating induction.
