abstract = {The surface chemistry and bulk chemical speciation of solid
industrial wastes containing 8 $wt-\%$ antimony (Sb) were
investigated using synchrotron X-ray Absorption Near Edge
Structure (XANES) and Time-of-Flight Ion Secondary Mass
Spectrometry (ToF-SIMS). Leaching experiments were conducted
in order to better understand the behavior of Sb in waste
streams and to inform regulatory management of
antimony-containing wastes. The experiments also demonstrate
how a combination of XANES and ToF-SIMS adds value to the
field of waste investigations. Leaching treatments (acid and
base) were performed at a synchrotron over 24 h time
periods. Surface analyses of the wastes before leaching
showed the presence of Sb associated with S and O. Bulk
analyses revealed Sb to be present, primarily, as trivalent
sulfide species. Both acid and base leaching did not change
the antimony speciation on the solid. Leaching transferred
about $1\%$ of the total Sb into solution where Sb was found
to be present as Sb(V). XANES data showed similarities
between leachate and FeSbO$_4$. During base leaching, the Sb
content in solution gradually increased over time, and
potential desorption mechanisms are discussed.},
