Abstract:Plants are more and more frequently used to control or remediate radionuclide pollution, plant extraction
is currently a more studied phytoremediation technology for remediation uranium-contaminated soil, the use of chela⁃
tion-induced enhanced phytoremediation technology can significantly improve the accumulation capacity of plants on
uranium, this paper expounds the types of chelating agents commonly used in phytoremediation of heavy metal contami⁃
nated soil, the chelating agent strengthens the phytoremediation mechanism, the accumulation ability of plants on urani⁃
um under the action of chelating agents and the ecological and environmental risks caused by chelating agents.
