Transport Studies of Biocompatible Polymeric Membrane and its Application in Lead Ion (Pb⁺⁺) Absorption

Contamination of these heavy metal ions in water has also increased public concerns because of their toxicity even at lower concentrations, besides non-biodegradability and tendency of bioaccumulation. Biodegradable natural composite membrane systems based on Polycaprolactone, (PCL), salt and montmorillonite (MMT) clay have been synthesized by phase inversion technique for the application of biomedical, technical and heavy metal ion absorption. The composite membrane provides better thermal stability and other medical properties than the pure PCL polymer film. This work will be valuable for understanding of development and characterisation of membranes and their application in heavy metal absorption. The absorption of heavy metal from water is a result of chemical reaction or interaction between the heavy metals and (Si-OH i.e. silanol) and (Al-OH i.e. aluminol) groups. In addition, it is helpful in developing economic and high performance material. Polymer nanocomposite electrolyte membranes were studied by X-ray diffraction (XRD), Fourier transformed Infrared (FTIR) technique, Raman spectroscopy and Impedance analysis. The heavy metal absorption behaviour is studied by the FT-IR spectroscopy. (C) 2021 Published by Elsevier B.V.
