Speciation and mobility of potentially toxic elements in municipal solid waste incineration bottom ash

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademic

Abstract

Bottom ash (BA) is the main residue from municipal solid waste incineration (MSWI), which can have some applications in construction materials, but is mostly landfilled in many countries. The main problem is the high concentration of potentially toxic elements (PTEs), particularly in the fine fractions (1-4 mm), that can leach from the material. In order to solve this problem with effective treatments, it is necessary to investigate the speciation of these PTEs. For this reason quantitative XRD analysis and sequential extraction were performed to track the liberation of PTEs in different chemical environments designed to dissolve specific phases.
