Leaching of metals from fly ashes in the presence of complexing agents

Original language description

The leachability of some metals (Al, As, Ba, Ca, Cr, Cu, Fe, K, Mg, Mn, Ti, Zn) from fly ashes was studied in the presence of ethylenediamine tetraacetic acid (EDTA) and naturally occuring complexing agents - humic acids (HAs). Secondary complex-formingequilibria taking place in the leachates increase significantly the leached amounts of most metals. Kinetic experiments showed that almost whole "available" amounts of metals are leached from fly ash within a time period of several hours (mostly within 20 h), with exceptions of matrix constituents (typically aluninium), which are released more slowly.
