Resumen:
Based on statistical physics parameters, the equilibrium biosorption of Ag ions on grape peel (GPE), grape seeds (GSE), and grape stem (GST) was analyzed by the Hill model. It was described experimentally and theoretically the adsorption process at molecular level. For this objective, a network of adsorption isotherms was well recorded at different temperatures from 298 to 328 K. New explanations were deduced by investigation of the number of adsorbed ions per site (n), anchorage number (n´), concentration at a half saturation (c1/2), molar adsorption energy (ΔEa), and monolayer adsorbed quantity (Q0).
