“…The TG/DTG data are in agreement with this assumption. [28][29][30][31][32] The thermal degradation of all synthesized biomembranes occurs in three main steps. During the first one that occurred over a temperature range 200-250 °C, these membranes lost about 20 wt% of their initial mass with a T max at about 242 °C and T onset at 213 °C.…”

Polymeric materials have been remarkably associated with our daily life. The hydrophilic/hydrophobic biopolymer systems have gained importance in the last few years, because of the environmental pollution of nonbiodegradable synthetic plastics. Recently, biopolymers with functional groups have been directly used for the fabrication of adsorptive membranes in order to avoid the undesirable morphology change of the membranes during the surface modifications. Compared with other modification technologies or a synthesis of totally new materials, biopolymer blending has several advantages like simplicity, reproducibility, and commercial feasibility. The valuable part of blending of biopolymers can be used for the preparation of new materials with improved physicochemical and mechanical properties. The objective of this work is the development of biomembranes based on a mixture of three biopolymers, that is, alginate (AL), chitosan (CS), and polylactic acid (PLA). Physical characterizations of the elaborated biopolymeric membranes are carried out by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and contact angle measurements. The SEM results show that the synthesized membranes exhibited homogeneous dense microstructures. The second objective of this paper is to evaluate the importance of these biopolymers in removing lead which is considered as toxic metal. In fact, all synthesized membranes are applied to the treatment of wastewater to eliminate heavy metals principally

“…Effort has been directed towards the development of such membranes and some promising materials and designs have been described. Metal ion separations using plasticized cellulose triacetate (CTA) membranes currently are receiving considerable attention [8][9][10][11][12]. In order to reduce the amounts of reactants and energy needed for separation and to decrease the environmental and economic…”

Polymer inclusion membranes used for selective transport and separation of metallic ions have emerged in recent times. Their expansion depends on the method of preparation and the study of their structure. In this paper, an improvement of a novel category of membrane for performing toxic ions elimination was reported. Different membranes were synthesized using a mixture of polymers: polysulfone (PSu) and cellulose triacetate (CTA), Dioctylphtalate (DOP) was used as a plasticizer and Di-(2-ethylhexyl) phosphoric acid (D2EHPA) was incorporated into the polymers as carrier to increase specific interactions between the different components. The membranes (polymers-plasticizer-carrier) were synthesized using a new method and characterized by various techniques including Fourier Transform Infrared (FTIR) spectroscopy, X-Ray Diffraction (XRD), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM) and contact angle. As the plasticizers' molecules were hydrophobic; their location at the surface of the modified polymeric membranes should modify the contact angle. Overall, our results showed that the addition of plasticizer with two polymers resulted in a homogeneous and hydrophobic membranes. A study of transport of Pb(II) and Cd(II) using synthesized membranes was studied. Dialysis experiments of lead and cadmium ions across a polymer inclusion membrane have proved a good performance.
