Extraction and/or recovery of chromium (Cr) and nickel (Ni) from textiles industry wastewater by membrane separation using polymer inclusion membranes (PIMs) based on polymer supports polyvinylidene fluoride (PVDF) and polyvinyl pyrrolidone (PVP), with Nitrilotriacetic acid (NTA) as extractive agent (EA). Furthermore, to quantify the PIMs performances, the macroscopic parameters such as the membrane permeability, P, and the initial flux, J 0 , and the microscopic parameters such as the association constant, Kass, and the apparent diffusion coefficient, D*, were determined based on the Fick's first law and the saturation law of the EA by the substrate (S). Also, to explain the substrate (S) (Cr or Ni) recovery process performed by the membrane, and to elucidate the mechanistic aspects, the activation parameters such as the energy Ea, the enthalpy ΔH ≠ and the entropy ΔS ≠ , were determined. The efficiency of different PIMs to recover Cr and Ni was compared. Respectively, the influence of temperature and pH on removal performance was investigated. The results showed that the macroscopic and microscopic parameters increased with increasing temperature and acidity medium. Similarly, the values of the activation parameters make it possible to explain the membrane performance and to elucidate the mechanism relating to the diffusion of the extracted substrates through this membrane.

“…The process depends on the association and the dissociation of the substrate-extractive agent entity ( ST ) at the membrane-solution interfaces and in the membrane phase during the substrate diffusion. To quantify the processes carried out and to study the performances of the adopted membranes, kinetic and thermodynamic models based on the first and second Fick’s laws and a saturation law of the extractive agent ( T ) by the substrate ( S ) have been developed in the laboratory [ 37 , 40 , 56 – 58 ]. The equilibrium “association/dissociation” is presented according to the following relationships.…”

Background Paracetamol compound remains the most used pharmaceutical as an analgesic and antipyretic for pain and fever, often identified in aquatic environments. The elimination of this compound from wastewater is one of the critical operations carried out by advanced industries. Our work objective was to assess studies based on membrane processes by using two membranes, polymer inclusion membrane and grafted polymer membrane containing gluconic acid as an extractive agent for extracting and recovering paracetamol compound from aqueous solutions. Result The elaborated membrane characterizations were assessed using Fourier-transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). Kinetic and thermodynamic models have been applied to determine the values of macroscopic (P and J0), microscopic (D* and Kass), activation and thermodynamic parameters (Ea, ΔH#, ΔS#, ΔH#diss, and ΔH#th). All results showed that the PVA–GA was more performant than its counterpart GPM–GA, with apparent diffusion coefficient values (107D*) of 41.807 and 31.211 cm2 s−1 respectively, at T = 308 K. In addition, the extraction process for these membranes was more efficient at pH = 1. The relatively low values of activation energy (Ea), activation association enthalpy (ΔH≠ass), and activation dissociation enthalpy (ΔH≠diss) have indicated a kinetic control for the oriented processes studied across the adopted membranes much more than the energetic counterpart. Conclusion The results presented for the quantification of oriented membrane process ensured clean, sustainable, and environmentally friendly methods for the extraction and recovery of paracetamol molecule as a high-value substance.

Background: Paracetamol compound remains the most used pharmaceutical as an analgesic and antipyretic for pain and fever. It has been detected in aquatic environments. The recovery of this compound from wastewater is one of the important operations carried out by modern industries. Its recovery is especially important for environmental protection. Currently, research is focused on membrane technology that has gained considerable interest over the last decades due to the various advantages that it presents.Result: Our work reports the selective extraction of paracetamol from liquid solution using two types of affinity polymer membranes: (i) polymer inclusion membrane (PIM) and (ii) grafted polymer membrane (GPM). The same extractive agent, gluconic acid (GA), is used for both. After total characterization, the developed membranes were adopted. Kinetic and thermodynamic models have been used to determine the values of various macroscopic parameters, permeability (P), and initial flux (J0), to understand the membrane performance. The same techniques have been used to determine the values of different microscopic parameters, association constant (Kass), and apparent diffusion coefficient (D*) that determine the interaction between the paracetamol substrates and the extractive agent, necessary for the diffusion of paracetamol molecules through the membrane. Similarly, the effects of initial concentration (C0), acidity (pH), and temperature were examined.Conclusion: The experimental results allow the determination of values of activation and thermodynamic parameters (Ea, ΔH#, ΔS#, ΔH#dis, and ΔH#th). The results explain the membrane performances and confirm that the energetic or kinetic aspects control the mechanisms related to the oriented processes. The results also indicate that it is possible to recycle wastewater and eliminate contaminants such as paracetamol.
