preparation and characterization of activated carbon derived from olive stone as adsorbent for congo red

carbon activated powdered was prepared from activated carbon derived from olive stone. then byusing the surface methodology, many parameters such as ph, furnace temperature (t), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. in addition, the adsorption of congo red onto the activated olive stone carbonactive was studied and removal or adsorption percent as response was reported. by applying surfacemethodology we obtained optimum conditions, at the other hand next researches can use theseconditions to produce activated carbon by high efficiency from olive stone as natural adsorbent.
