Abstract
- In order to improve the high added values and solve the environmental pollution problems of the waste edible oil (EO) and discarded cigarette butt (CB), the CB-derived activated carbons (ACs) were prepared by H<subscript>3</subscript>PO<subscript>4</subscript>, KOH, and CO<subscript>2</subscript> activation methods and used as an adsorbent for the decolorization of waste EO. The CB-AC@H<subscript>3</subscript>PO<subscript>4</subscript> prepared by H<subscript>3</subscript>PO<subscript>4</subscript> activation method had the high surface area of 1423 m<superscript>2</superscript>/g, oxygen contents of 11.24%, and yield of 14.11%, and exhibited better decolorization performance for EO than the CB-AC@KOH and CB-AC@CO<subscript>2</subscript>. The optimal decolorization process parameters of CB-AC@H<subscript>3</subscript>PO<subscript>4</subscript> based on the orthogonal experimental results were the AC contents of 8%, the decolorization temperature of 90 °C, and the decolorization time of 30 min, which resulted in the corresponding decolorization rate of 83%. Therefore, these provided one application case for turning waste into wealth, energy conservation, and emission reduction. [ABSTRACT FROM AUTHOR]
