The efects of soaking time, microwave power, radiation time, activator concentration on the quality of activated carbon were researched. determine the optimal conditions by the single factor experiments : When us ing ZnC1 2 as activator, microwave power was 560W,radiation time was 3 min,ZnCl 2 solution concentration was 40%,Soaking time was iodine adsorption value reached mg · g-1 and yield reached % with the optimal process. When us ing NaOH as activator, microwave power was 560W,radiation time was 3 min, NaOH solution concentration was 40%,Soaking time was iodine adsorption value reached mg · g-1 and yield reached % with the optimal process. Experimental results show the use of ZnC1 2 as an activator to activated carbon better than the use of NaOH.
