Preparation and characterization of activated carbon from bio-char by chemical activation with ZnCl_2

High surface area activated carbons were prepared with bio-char as raw material and Zn Cl2 as activating agent. Effects of impregnation ratio,activator concentration,activation temperature,and activation time on the adsorptive capacity of activated carbon were studied. The properties and pore structure of the carbon were characterized with nitrogen adsorption-desorption,scanning electron microscopy(SEM),infrared spectroscopy(FT-IR),power X-ray...
