Statistical Physics Modeling of Sorption Isotherms of Aluminum, Iron, and Indium on Tetraphenylporphyrin (H₂TPP) and Tetrakis(4-tolylphenyl)porphyrin (H₂TTPP): Phenomenological Investigation of Metalloporphyrins at the Molecular Level

Table 4

Values of the physicochemical variables (, , , , , , , and ) deduced from the fitting of experimental data of AlCl₃, FeCl₃, and InCl₃ on tetraphenylporphyrin H₂TPP (systems (a), (b), and (c)) with the three adopted models.
