چکیده
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.

متن کاملPreparation and characterization of Montmorillonite/ZrO2 nanocomposite and its application for removal of Congo red
Montmorillonite/ZrO2 nanocomposites were prepared by the sol-gel method underultrasonic irradiation. The montmorillonite was incorporated into Zirconium gel. After stirring for 24 hr, the mixture was irradiated for 30 min under ultrasonic irradiation. The filtrated composite gel was calcinated at 400°C for 3h in furnace. The morphology of prepared catalysts was characterized by field emis...
متن کاملSorption of Cu(II), Zn(II) and Ni(II) from aqueous solution using activated carbon prepared from olive stone waste
The performance of olive stone activated carbon (OSAC) for sorption of Cu2+, Zn2+ and Ni2+ ions was investigated via batch technique. OSAC materials were prepared under different physially activation conditions. Olive stone waste was physically activated with N2 gas and steam gas at 900oC at 3.5h hold time (OSAC-3) was choice as the best one for Cu2+, Zn2+ and Ni2+ removal. Characterization for...
متن کاملRemoval of Congo red dye from aqueous solutions by a low-cost adsorbent: activated carbon prepared from Aloe vera leaves shell
Background: Synthetic dyes have several harmful effects on human health as well as aquatic life. In this study, activated carbon (AV-AC), based on Aloe vera leaf shells, was used as a novel agricultural adsorbent, one that is low-cost and available for the removal of Congo red (CR) as a carcinogenic dye from aqueous solutions. Methods: In the batch system, the influence of different paramete...
متن کاملRole of activated carbon from natural adsorbent for removal of textile dyes: effect of pH, kinetic and adsorbent mass
In the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(ACW) towards Direct Red 81 (DR81) and Direct Blue 71 (DB71) for the removal from aqueous solution. Thesorption study of ACW at the solid-liquid interface was investigated using kinetic, sorption isotherms, pH effectand amount of adsorbent. Experimental data were analyzed by Langmu...
