Abstract
The adsorption of reactive dye onto activated carbon obtained from cow bones was investigated. The effects of dye concentration and pH on the adsorption of the dye onto the activated carbon were similarly investigated. The optimum adsorption was obtained at dye concentration of 45 mg/L and pH 6 respectively. Langmuir and Freundlich adsorption isotherms were employed to provide qualitative information on the capacity of the adsorbent as well as the nature of the solute-surface interaction. The correlation coefficient obtained for Freundlich isotherm (R2 = 0.6369) and Langmuir isotherm (R2 = 0.5823) indicates that Freundlich isothermal model is more fit for the adsorption process. By implication, the adsorption of Reactive Yellow FG onto the activated carbon can be referred to as a multilayer adsorption since the assumption of Freundlich’s equation is based on heterogeneous distribution of active sites.
