A batch experiment was conducted to investigate extracting efficiency of six extracting agents (glycine, glutamic, cysteine, EDTA, Citric scid and thiourea) to heavy metals, arsenic and fluorinion in contaminated soils. The result showed that the best extracting efficiency of Pb, Cr, Cu, Cd and Mn, Zn were EDTA and Citric acid, respectively. The extracting efficiency of EDTA to heavy metals in an order was Pb〉Cr〉 Cu 〉Cd. For the extracting analysis of arsenic and fluorinion, the concentration of extracting agents is decided to be 0, 2.5, 5...
