Co-stabilization of Pb/Cu/Zn by beneficial utilization of sewage sludge incineration ash: Effects of heavy metal type and content
Abstract
Pb was more easily interacted with Al, Si and P to form PbAl2Si2O8 and Pb3(PO4)3. Zn and Cu were largely incorporated in crystal phases with spinel structure. Heavy metal type and content affected the phase composition and metal leaching. Practical application can be promoted by achieving heavy metal coimmobilization.
