| Résumé: | Thermodynamic parameters ΔG°, ΔH° and ΔS° are indicators of the possible nature of adsorption. This review summarizes the thermodynamic properties of metal adsorption by green adsorbents. Conclusively, the adsorption of heavy metals ions by green adsorbents is spontaneous in most cases (ΔG° < 0). Since the thermodynamic parameters were evaluated from very different adsorbent/adsorbate combinations, it is not possible to note a correlation between the corresponding enthalpy change (ΔH°) and entropy change (ΔS°) following adsorption |
