Activated Carbon Prepared from Eztracted Sawdust Waste with KOH Activation
Introduction Commercial activated carbon is a preferred adsorbent for the removal of micropollutants from the aqueous phase. Nevertheless, its widespread use is restricted due to its high cost. To decrease treatment cost, attempts have been made to find inexpensive alternative activated carbon precursors, such as waste materials. All materials with high carbon content can be used as raw materials for activated earbon production. Wood, lignite coal, coconut shell, and peat are some of the raw materials currently used to prepare activated carbons. The development of methods to re-use waste materials is greatly desired and the production of activated carbons from waste materials is attractive. There has been increasing interest in producing activated carbons from agricultural and forest wastes. Their advantages as carbon feedstock include availability as renewable resources, low ash content, reasonable hardness, and their ability to produce granular activated carbons of high adsorption capacity. Due to their particular porous characteristics, woody materials are very relevant and attractive raw materials to prepare HSA activated carbon for the adsorption of pollutants in the liquid phase.
