4DescriptionAbstract The adsorption behaviour of acid orange-7 from aqueous solution onto activated carbon prepared from bentonite was investigated under various experimental conditions. To evaluate the adsorption capacity, initial dye concentration, contact time, effect of solution pH and adsorbent dosage were investigated in the batch mode. Experimental isotherm data was represented with Langmuir and Frendlich adsorption isotherms models. The adsorption data were found to follow the Langmuir model better than the Frendlich model. The result showed that this novel adsorbent had a high adsorption capacity (Qo=238.0952 mg/g) making it suitable for use in the treatment of Acid orange-7 enriched wastewater.
