Author(s): Kumar Sujata, Singh D, Mishra A.K, Upadhyay M, Kumar Saroj
Abstract: In the present study, adsorption characteristics of red mud to remove Cu(II) ion from aqueous solutions have been evaluated under batch mode experiments. To have an idea about the nature of adsorption, Freundlich and Langmuir adsorption isotherm models have been discussed. To know the order of reaction Lagergren pseudo first order and pseudo second order equation have been employed and discussed. Intraparticle diffusion model have been discussed to have an idea of the mechanism of adsorption. Spontaneity and feasibility of the process have been discussed using thermodynamic parameters such as change in free energy, change in enthalpy and change in entropy. Activation energy of the process and sticking probability have been calculated and discussed.
