This study deals with an experimentation performed with the aim to assess the feasibility of a process for the remediation of copper and iron contaminated soil. Experimental tests were carried out on an artificially contaminated soil, the leaching of copper and iron was performed by flushing an aqueous solution of EDTA: the conditions for metals extraction were evaluated. The effectiveness of soil conditioning prior EDTA extraction was also investigated. Results show that a preliminary soil conditioning with the NaNO3 solution was necessary to avoid variations in soil permeability and to allow the percolation of the extractant solution.
