Ks. Wang et al., FATE AND PARTITIONING OF HEAVY-METALS AFFECTED BY ORGANIC CHLORIDE CONTENT DURING A SIMULATED MUNICIPAL SOLID-WASTE INCINERATION PROCESS, Journal of environmental science and health. Part A: Environmental science and engineering, 32(7), 1997, pp. 1877-1893
The effect of organic chloride derived from PVC and other possible sou
rces in wastes, on the partitioning and speciation of heavy metals and
their compounds, during Municipal Solid Wastes (MSW) incineration was
studied using a laboratory tube furnace and simulated waste spiked wi
th organic chloride. The results indicated that an increase in the org
anic chloride content and combustion temperature might increase the vo
latility of heavy metals and/or their compounds in the wastes, thus, i
ncreasing metal partitioning in the fly ash or the flue gases. Metal o
xides were the major metal species found in the bottom ash, as identif
ied by X-ray diffraction (XRD) analysis, regardless of the addition of
organic chlorides, while several other metal chlorides were also foun
d when spiked at higher concentrations.
