Abstract

The adsorption of a mono azo dye methyl-orange (MeO) onto granular pinecone derived ACTIVATED CARBON (GPAC), from aqueous solutions, was studied in a batch system. Seven two-parameter isotherm models Langmuir, Freundlich, Dubinin-Radushkevic, Temkin, Halsey, Jovanovic and Hurkins-Jura were used to fit the experimental data. The results revealed that the adsorption isotherm models fitted the data in the order of Jovanovic (X2=1.374) > Langmuir > Dubinin-Radushkevic > Temkin > Freundlich > Halsey > Hurkins-Jura isotherms. ADSORPTION ISOTHERMS modeling showed that the interaction of dye with ACTIVATED CARBON surface is localized monolayer adsorption. A comparison of KINETIC MODELS was evaluated for the pseudo-second order, Elovich and Lagergren KINETIC MODELS. Lagergren first order model was found to agree well with the experimental data (X2=9.231). In order to determine the best-fit isotherm and KINETIC MODELS, two error analysis methods of Residual Mean Square Error and Chi-square statistic (X2) were used to evaluate the data.
