A new grafted polymer membrane (GPM) was used to study the oriented process of facilitated extraction Glucose, Fructose, and Sucrose from the sugar industry discharges. The GPM was elaborated with polysulfone (PSU) and poly(1-vinylpyrrolidone) (PVP) supports containing Gluconic acid (GA), as extractive agent. The membrane was prepared by the phase inversion method after dissolution of the various constituents. Morphology and composition of the membranes, with and without extractive agent, were investigated using respectively, scanning electron microscopy (SEM) analysis and Fourier Transform Infrared (FTIR) spectra. The influence of substrate nature and concentration as well as the influence of temperature factor on the performance of this studied process were carried out through the adopted membrane.
Macroscopic parameters (permeability P and initial flux J0) and microscopic parameters (association constant K !@#$%^&* and apparent diffusion coefficient D*) related to the oriented process of facilitated extraction of these substrates through this membrane type were determined. The selectivity of this membrane type for the extraction of the glucose substrate was confirmed by the notable difference between...
