In this work, ultrasonic probe sonication (UPS) and microwave-assisted extraction (MAE) were used for rapid single extraction of Cd, Cr, Cu, Ni, Pb and Zn from soils polluted by former mining activities (Mónica mine, Bustarviejo, NW Madrid, Spain), using 0.01 mol L-1 calcium chloride (CaCl2), 0.43 mol L-1 acetic acid (CH3COOH) and 0.05 mol L-1 ethylenediaminetetraacetic acid (EDTA) at pH 7 as extracting agents. The optimum extraction conditions by UPS consisted of an extraction time of 2 minutes for both CaCl2 and EDTA extractions, and 15 minutes for CH3COOH extraction, at 30% ultrasound amplitude, whereas in the case of MAE, they consisted of 5 minutes at 50 ºC for both CaCl2 and EDTA extractions, and 15 minutes at 120 ºC for CH3COOH extraction [5]. Extractable concentrations were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). The proposed methods were compared with a reduced version of the corresponding single extraction procedures proposed by the Standards, Measurements and Testing Programme (SM&T). | |
