Thermal immobilization of Cr, Cu and Zn of galvanizing wastes in the presence of clay and fly ash.

Abstract

In the present investigation thermal treatment of galvanizing waste with clay and fly ash has been carried out to immobilize Cr, Zn, Cu and other metals of the waste at temperature range 850 degrees C to 950 degrees C. Leaching of the metals from the waste and solidified product was analyzed using toxic characteristic leaching procedure (TCLP). Results… (More)
