Ky. Chiang et al., CHLORIDE EFFECTS ON THE SPECIATION AND PARTITIONING OF HEAVY-METAL DURING THE MUNICIPAL SOLID-WASTE INCINERATION PROCESS, Science of the total environment, 203(2), 1997, pp. 129-140
This study examines the effects of chloride on the partitioning and sp
eciation of heavy metal during waste combustion by using simulated mun
icipal solid wastes (MSW). The results indicate that increasing the ch
loride content of the waste and the combustion temperature may cause t
he formation of volatile heavy metal compounds, thus increasing metal
partitioned to the fly ash and the flue gases. As identified by X-ray
diffraction (XRD), speciation is found to be primarily influenced by t
he reactive affinity of the heavy metals, the types of chlorides, and
the metal concentrations in the waste. (C) 1997 Elsevier Science B.V.
