Adsorption Studies of Ni(II) from Aqueous Solution onto Bentonite
Abstract A flame atomic absorption method was employed to study the removal of Ni(II) from aqueous solution onto bentonite surface, using the batch equilibrium method. Maximum removal (80%) was achieved from a solution of pH 3.2. Effect of various parameters like concentration, shaking time and temperature were examined to achieve the optimized conditions of maximum recovery of Ni(II) from solution by adsorption method. The effect of various anions and cations on the recovery of Ni(II) was also investigated. The data were investigated in terms of calculating thermodynamic quantities and were found to fit well to Freundlich equation.
