Abstract
As a first step in the development of ligand-assisted removal of heavy metals from municipal solid waste incineration bottom ash under alkaline conditions, ammonium nitrate, ammonium sulfate, ammonium acetate, ammonium oxalate, ammonium citrate, urea, and mixtures of ammonium salts and urea were examined to find which ligands could promote the leachability of elements, including heavy metals, and which elements could be mobilized through complexation. Ammonium citrate promoted the mobilization of Cr, Cu, Mn, P, Sb, and especially Fe. Ammonium nitrate accelerated Mg leachability significantly. Under the conditions used in this study, counter anions seemed to contribute mainly to the complexation. When a mixture of ammonium citrate and urea was utilized, a coexistence effect appeared on Fe mobilization. Although the correlation analysis of leaching test results showed a strong correlation among Cr, Cu, Fe, Mn, and P, X-ray diffraction analysis partially supported the correlation between Fe and Mn only.
