| Abstract: | The various process conditions of activated carbon were prepared from waste poplar sawdust by phosphoric acid-sulfuric acid activation which used phosphoric acid as main activator and concentrated sulfuric acid as auxiliary activator according to orthogonal test. The experiment determined the methylene blue decolorizing power and iodine adsorption value of activated carbon,the influence of activating factors on the yield and adsorption properties of activated carbon was studied. The experimental results showed that the optimum process conditions of preparation of sawdust active carbon by phosphoric acid-sulfuric acid activation are impregnation ratio 1 ∶ 2. 5, impregnation concentration 60%, activation time 90 min, activation temperature 550℃. |
