    Studies of Adsorption of Heavy Metals onto Spent Coffee Ground: Equilibrium, Regeneration, and Dynamic Performance in a Fixed-Bed Column by N. E. Davila-Guzman, F. J. Cerino-Córdova, M. Loredo-Cancino, J. R. Rangel-Mendez, R. Gómez-González, E. Soto-Regalado

    Published 2016-01-01
    “…Moreover, the applicability of a mass transfer model based on external mass transfer resistance, axial dispersion, and ion-exchange isotherm was evaluated, and the results were in good agreement with the experimental data for the adsorption in SCG packed column. The sensitivity analysis of the model parameters showed that axial dispersion coefficient is the most significant parameter in the dynamic simulation. …”
