- Abstract
In the present work, we prepared three polymer inclusion membranes (PIM), based on polyvinyl alcohol (PVA) as polymeric support and containing three extractive agents: Nitrilotriacetic acid (NTA), Ethylene diamine tetra acetic acid (EDTA) and tris (2-aminoethyl) amine (TREN). The morphology structures of these membranes were determined using different spectroscopical techniques by Fourier-transform infrared spectrometry and scanning electron microscopy techniques. The membranes were used to conduct experiments of oriented extraction processes for the facilitated recovery of Nickel (II) ions from lithium-ion (Li-ion) battery waste. The obtained results allowed to determine the values of different macroscopic and microscopic parameters of paramount importance such as respective permeability (P), initial flux (J0) and apparent diffusion coefficient (D*), constant association (Kass) related to the movement of the substrate through the membrane. The influence of several factors, as the initial substrate concentration and temperature (C0, T) was studied. The results indicate that the different parameters (P, J0, D* and Kass) vary strongly with the temperature of the medium and that of the performances of the used membranes increase with the temperature factor. The activation and thermodynamic parameters (Ea, ΔH#ass and ΔS#, ∆Hth and ∆Hdiss#) were also determined and their values indicate a kinetic control for the mechanism of the studied processes, which explains the high performances of the developed membranes and indicates a mechanism by successive jumps of Nickel (II) ions on fixed sites of the extractive carriers immobilized in the membrane phase.
