Keywords: | Agriculture improver;Bioavailability index;Extraction method;Leached;Metals | Issue Date: | 2017 | Publisher: | ALMA MATER Publishing House, “VASILE ALECSANDRI” University of Bacău | Abstract: | This study presents a modified extraction method for evaluation of mobile fraction from sewage sludge samples. The mobile content of As, Cd, Co, Cr, Cu, Mo, Ni, Pb, Sb, Se and Zn was detected using three different single chemical extraction procedures and also the leaching test according to SR EN ISO 12457-2/2003 standard. The experimental data show that the optimal extraction method was the one with diethylenetriamine pentaacetic acid (DTPA), CaCl2 and triethanolamine (TEA) and a modified ratio solid: solution = 1 : 10 (mass per volume). The selected method provides a better assessment of the ability of metals to leach from sewage sludge during storage than leaching test method. |
