Abstract

The activated carbon was prepared from soybean straw by activation of zinc chloride. Porosity characterstics were determined from the analysis of N2 adsorption isotherms using BET and BJH method. Microstructure of the sample was examined using a scanning electron microscopy.The results showed that the best sample of activated carbon was obtained under the conditions: the impregnation ratio of 3; impregnation time of 20h, activation temperature of 500 and activation time of 90min.The iodine adsorption value, methylene blue adsorption value and phenol adsorption value were 750.67 mg/g, 168.01 mg/g and 205.36 mg/g, respectively. Activated carbon has high BET surface area(1526.54 m2/g) and whole pore volume(0.876cm3/g) with average pore diameter of 3.413nm.
