Abstract :Chemically enhanced phytoextraction has been proposed as an effective approach to removing heavy metals from contaminated soil through the use of high biomass plants. This research is to test the effect of the applications of EDTA and DTPA insert ignore into journalissuearticles values(0, 4, 8 mmol kg-1); on the phytoextraction of maize insert ignore into journalissuearticles values(Zea mays); and sunflower insert ignore into journalissuearticles values(Helianthus annuus); grown in Pb contaminated soil. The addition of a chelate, 8 mmol/kg ethylenediamine-tetracetic acid insert ignore into journalissuearticles values(EDTA);, increased the proportion of phytoavailable Pb in the soil insert ignore into journalissuearticles values(dissolved in soil solution and exchangeable from soil colloids);, and also their uptake by tested plants up to 11 times insert ignore into journalissuearticles values(Zeya mays);, 19 times insert ignore into journalissuearticles values(H.annus); respectively compared to the control.
