| Abstract: | Applying chelating agents into the soil to promote plant absoption of heavy metals is currently a very promising technology of soil remediation.A review was presented of the application of chelating agents in the phytoremediation of heavy metal contaminated soils by the way of discussing the mechanism and characteristic of phytoremediation.The mechanism is that hyperaccumulators can enrich heavy metals,but there are some shortage in the phytoremediation.In this paper,the mechanism of chelation-enhanced phyt... |
