Abstract—Making use of jujube kernel as the main material, For preparing activated carbon, conventional heating
jujube kernel activated carbon was prepared with a method is usually adopted, in which the energy is produced by
microwave-induced activation process using phosphoric acid and electrical furnace. Recently, microwave heating technology has
zinc chloride as the activating agent. The effects of various been applied to fabricate activated carbon due to its heatin
factors such as microwave power, radiation time,activation grapidly and uniformly. Many peoples have reported the
agent/carbon ratio and activation agent concentration on the preparation of high surface area activated carbon using
activation have been studied. Experimental results indicated that microwave radiation[7-8]. However, as far as we know, there
the optimum conditions for phosphoric acid as activation agent are very few reports on the preparation of activated carbon
by microwave-induced were as follows: microwave power 600W, from jujube kernel by microwave heating.
