In the present study, Bentonite has been used as adsorbent to remove Cd(II) ions from wastewater. The effect of different parameters such as initial Cd(II) ion concentration, temperature, pH have been studied. For kinetic study, Lagergren first order and pseudo second order equation have been used. For equilibrium study, Langmuir and Freundlich equation has been discussed. Thermodynamic parameters such as entropy change, enthalpy change, and Gibbs free energy change have been calculated and discussed.
