This study compares the effect of synthetic aminopolycarboxylic acids ethylenediamine tetraacetate (EDTA) and diethylenetriamine pentaacetate (DTPA) with natural low-molecular-weight organic acids (LMWOAs) oxalic acid and citric acid as chelators for enhancing phytoextraction of Cr and Ni by Brassica juncea on serpentine-mine tailings. Chelator treatments were applied at doses of 0.05 and 0.10 mmolkg(-1) dry soils after seedlings were grown in pots for 56 days. Experimental results indicate… CONTINUE READING
