Abstract

In this study the effect of physical mixing cigarette filters with KOH powder on the characteristics of the final carbonized porous carbon has been evaluated. The results were compared to that without any impregnation. The final carbonized product was studied using scanning electron microscopy (SEM), Energy dispersive X-ray spectroscopy (EDX) and adsorption-desorption analysis. It was found that dry KOH physical mixing of cigarette filters would decrease the specific Brunauer, Emmet, and Teller (BET) surface area by around 79%. This suggests that dry KOH impregnation of cigarette butts as carbon precursor for the synthesis of porous carbon would not be a suitable approach in obtaining higher BET surface area.
