英文摘要：

A series of activated carbons were prepared with coconut shell as raw materials and zinc chloride as activating agent,employing microwave radiation heating method.The effects of processing variables such as the microwave power,radiation time,impregnation time and concentration of ZnCl2 aqueous solution on the yield and adsorption properties of the products were systematically studied.An orthogonal test was designed to optimize the preparation conditions.When the radiation power was 900 W,activation time was 9 min,concentration of ZnCl2 was 50（wt） % and impregnation time was 48 h,the resulting product had an iodine adsorption value of 1258.34 mg/g and a methylene blue adsorption value of 200.00 mL/g.Its BET surface area and total pore volume were 1395.46 m2/g and 0.7021 mL/g,respectively.The pore size predominantly ranged from 4 to 9 nm.
