Morus albaL. as raw material,Morus albaL.-based activated carbon used for adsorbing phenol by microwave irradiation activated with zinc chloride. Under the condition of the microwave power was 800 W,solution mass fraction was 50%. The influence of microwave irradiation time,mass ratio of Zinc chloride to Morus albaL. ,time of Morus albaL. impregnated in ZnCl2 solution,pH value of ZnCl2 solution on the yield of active carbon and the phenol adsorption were investigated. The result showed that the opti-mum conditions for the preparation of activated carbon with ZnCl2 by microwave irradiation was obtained:the mass ratio of ZnCl2 to Morus albaL. was 3∶1. pH value of ZnCl2 solution was 2,dipping time was 20 h, microwave irradiation time was 25 min. In this preparation process conditions,the yield of active carbon was 37. 4%,the phenol adsorption value was 138. 3 mg/g and Cr6+ adsorption value was 7. 877 mg/g.
