Abstract:

The use of the monolayer model with two sites types was benefit for the energetic characterization of the tetracycline (TC) adsorption onto Agave americana activated carbon. This model equation is based on the grand canonical formalism of the statistical physics. The low values of the adsorption mean energies modulus ($$\left|{\Delta E}_{1}\right|$$) and ($$\left|{\Delta E}_{2}\right|$$) at different temperatures and the obtained adsorption energy distributions confirmed that the TC molecules are physisorbed onto the two activated carbon sites types. Moreover, the free Gibbs energy and the internal energy functions evolutions indicate the spontaneity and the exo-thermicity of the TC molecules adsorption on the two Agave americana activated sites types.
