Abstract

Factors of influencing properties of activated carbon such as activating agent, additives, power of microwave and activation time were systematically studied by means of orthogonalization. The best technology on manufacturing the activated carbon was obtained: the sawdust of pine was infused 48 hours in 20%35% phosphoric acid, in which 2%6% sulfuric acid and 2%4% hydrochloric acid were additive, and then radiated 1020 min by microwave at 600800W. The experiment showed that the yield of the activated carbon was 44%, the methylene blue decolourizing ability reached 1824 mL/0.1g
