The present study was undertaken to evaluate the feasibility of sugarcane bagasse for the removal of nickel from aqueous solution. Batch experiments were performed to study the biosorption of nickel on sugarcane bagasse sorbent considering the effect of contact time, initial concentration of nickel ions, pH of the solution and temperature. The sorption process was well explained with pseudo second-order kinetic model. The experimental maximum sorption capacity of sugarcane bagasse for nickel removal was approximately 2 mg/g at 25 °C and at pH 5. The biosorption data was fitted to Langmuir, Freundlich and Sips isotherm models. The Langmuir model showed better representation of data, with correlation coefficient greater than 0.99. The thermodynamics parameters were evaluated from the experimental data. The Gibbs free energy was determined to be negative, indicating the spontaneous nature of the sorption process. The results of the present study suggest that sugarcane bagasse waste can be used beneficially for nickel removal from aqueous solution.
