Abstract
Increasing amounts of petrochemical sludges that need to be disposed in a safe and economical way have become a very important issue in waste management. This study aimed to reduce leaching of heavy metals from petrochemical sludges using the vitrification method. The ashing temperature of 985oC was selected in preparing the ash of the dried sludge prior to the vitrification process at 1100oC to 1400oC. Scanning Electron Microscope (SEM), Thermogravimetric (TGA) and Toxicity Characteristic Leaching Procedure (TCLP) analyses were carried out on the vitrified samples. Some heavy metals namely Al, Au, Fe, Ni, Mn and Zn were found in the raw sludge. Results showed that the concentrations of Al and As decrease as the vitrified temperature increased. The vitrification method exhibited excellent output in immobilizing the transition metals leading to a reduction in environmental pollution caused by petrochemical sludge containing heavy metals.
