Adsorptive removal of a cationic dye – Rhodamine B – from aquoeus solutions was achieved by the use of Animal Bone Meal as a new low cost adsorbent. Adsorption of Rhodamine B was occured by studing the effects of contact time, adsorbent amount, dye concentration and temperature. Dye adsorption equilibrium was rapidly attained after 60 minutes of contact time. The isotherms of adsorption data were analyzed by Langmuir and Freundlich adsorption isotherm models. The adsorption capacity (Qm) obtained from the Langmuir isotherm plots were 62.11, 63.69, 64.13 and 64.95 mg/g respectively at 303, 313, 323 and 333°K. Thermodynamic parameters such as ΔH0, ΔS0 and ΔG0 were calculated, which indicated that the adsorption was spontanoeus and endothermic nature. The characteristic results and dimensionless separation factors RL showed that animal bone meal can be employed as an alternative to commercial adsorbents in the removal of Rhodamine B from aquoeus solution and wastewater.
