Effect of copper (Cu) and zinc (Zn) impregnation on the thermal stability of charcoal has been studied utilizing thermogravimetrey (TG) and differential thermal analysis (DTA) technique. The results indicate towards a decrease in thermal stability of charcoal upon impregnation. Energies of activation for decomposition of Cu and Zn impregated charcoal calculated from TG are 17.4kj/mole and 20.2kj/mole respectively.
