ABSTRACT
The objective of this study was to prepare the ferrite through microwave method using the residual ash of microwave pyrolysis wastewater sludge as doping raw materials. The effect of dopant on the absorbing microwave properties of ferrites was studied, and the solidification of heavy metal in the ferrite was also investigated. It can be expected that this study would be useful for further developing of effective reutilization strategy for various metals and SiO2 existing in the pyrolysis residual ash.
