“…It is proposed that the evolution of crystal phase in fly ash probably leads to the variety of heavy metal species (Wu et al, 2015). For the investigation of heavy metal distribution on fine particle, energy reflection of heavy metal was also performed by EDX.…”

Experiments and thermodynamic equilibrium calculations were performed to investigate the behavior of Cd during sewage sludge incineration. The chemical equilibrium calculations indicated that chlorine significantly increased the volatilization of Cd in the form of CdCl2. In addition, SiO2-containing materials can function as sorbents for stabilizing Cd. The effect of PVC added to the sludge on the migration of Cd in the sludge was greater than that of NaCl. As the temperature increased, both organic and inorganic chlorides reduced the Cd distribution in the bottom ash. The chloride concentration, and the incineration time exhibited insignificant changes in Cd emission. With the addition of either NaCl or PVC into the sludge, the phases of Cd present in the bottom slag were primarily present in the form of silica-alumina oxides or multi-metal oxide, which could inhabit the Cd volatilization.

“…Leaching of heavy metals from waste material depends on its bonding energy in the matrix as well as leaching condition (Haiying et al 2010;Singh & Lee 2015;Wu et al 2015). The speciation analysis of POC provides an idea about the capability heavy metals in POC to leach in different environmental conditions.…”
