“…It should be suggested that the tested porphyrin adsorb only one layer of cationic metal for AlCl 3 and FeCl 3 while, many adsorbed layers are formed in the case of InCl 3 . The multi-layers ionic adsorption of the indium chloride takes place via the layer by layer (LBL) process which is based on charge neutralization between particles having opposite charge signs (anions and cations) 20 , 29 .…”

“…Furthermore, the statistical physics models give information about the number of adsorbed layers during the adsorption mechanism whereas, the Langmuir model assumes that one adsorbed layer is formed during the adsorption process. It should be also mentioned that in the case of the multi-layers ionic adsorption, we have fundamentally to use a model that reflects a layer by layer adsorption 20 . The empirical models do not assess this supposition.…”

A quartz crystal adsorbent coated with 5,10,15,20-tetrakis(4-methylphenyl) porphyrin was used to examine the complexation phenomenon of three metallic ions [aluminum(III), iron(III) and indium(III)]. The aim is to select the appropriate adsorbate for metalloporphyrin fabrication. The equilibrium adsorption isotherms of tetrakis(4-methylphenyl) porphyrin were performed at four temperatures (from 300 to 330 K) through the quartz crystal microbalance (QCM) method. Subsequently, the experimental data were analyzed in order to develop a thorough explanation of the complexation mechanisms. The experimental results indicated that the aluminum(III) chloride is the adequate material for metalloporphyrin application. Theoretical investigation was established through physics adsorption models in order to analyze the experimental isotherms. The AlCl3 isotherms were modeled via a single-layer adsorption model which is developed using the ideal gas law. Whereas, the FeCl3 isotherms were interpreted via a single-layer adsorption which includes the lateral interactions parameters (real gas law), indicating the lowest stability of the formed iron-porphyrin complex. The participation of the chloride ions in the double-layers adsorption of InCl3 was interpreted via layer by layer formulation. Interestingly, the physicochemical investigation of the three adopted models indicated that the tetrakis(4-methylphenyl) porphyrin adsorption was an endothermic process and that the aluminum(III) chloride can be recommended for an industrial application because it presents the highest adsorption energy (chemical bonds with porphyrins).

Methylene blue adsorption on zeolitic imidazolate‐8 metal‐organic framework (ZIF‐8) according to basic phenomena Different Multiphysics modeling methodologies were combined to reveal understand the adsorption processes. Rather than their functional groupings, sorbents′ porosity is important, affects methylene blue adsorption, according to a statistical physics method. Quantum chemistry calculations imply the ZIF‐8 has dispersive interactions and pore properties. The examined reactive sites reveal that the for both electrophilic and nucleophilic assaults, ZIF‐8 has the same favored sites., that explains this adsorbent‘s highest performance. Finally, Monte Carlo simulations reveal Methylene blue adsorption on ZIF‐8 in the most stable energy configuration. Using XRD, IR, SEM, EDX, and nitrogen adsorption‐desorption, the prepared ZIF‐8 was characterized. The effectiveness of ZIF‐8 as an adsorbent which studied by researching MB removal from aqueous solutions as organic pollutants. The isothermal adsorption method suits the Langmuir model, and qmax=522.95 mg/g was the maximum adsorption power. The adsorption kinetics knowledge matched the pseudo‐second‐order model well. Accordingly, it is possible to use ZIF‐8 with high performance and superior stability to remediate wastewater from organic contaminants.

Adsorption is a major basic and applied phenomenon in many scientific disciplines. In particular, the design of adsorbents to remove pollutants from wastewater requires advanced knowledge of adsorption isotherms, which are useful tools to identify physicochemical factors that control adsorption performance. Recent modeling of adsorption isotherms has focused on the use of statistical physics. Here, we review the major adsorption isotherm models based on statistical physics. We discuss steric, energetic, and thermodynamic parameters.
