| Abstract: | Pot tests of phytoremediation of soil polluted artificially with heavy metals were conducted to investigate the effects of the remediation using Lolium L.through chemical enhancement.Chelate EDTA,Gallic are surfactant SDS were used as chemical enhancement factors.The soil leaching tests were also carried out to observe the potential risk of chemical enhancement in this study.Results show that the order of enhanced phytoextraction of Cd,Pb and Zn by single or complex dosing chelating agents and surfactant wa... |
