Abstract

Pectin has demonstrated a great potential to act as a matrix for a wide variety of applications, such as biomedical fields. This study aims to modify pectin with Poly(vinyl alcohol) (PVA) to fabricate new class of material for hemodialysis membrane application. In this study, Pectin-PVA membrane was prepared by addition of 4% PVA and filtration capacity of the membrane was tested for urea transport. The physic-mechanical properties of resultant Pectin-PVA membrane was also characterized by Tensile Test, Fourier Transform Infrared (FTIR), X-Ray Diffraction (XRD), and Scanning Electron Microscopy (SEM). The results showed that: (1). Pectin-PVA membrane was successfully synthesized, confirmed by FTIR spectra data of -OH, -CH2, -CH, -CO (ester), and C-O (ether) vibrations- (2). The addition of PVA significantly increased the membrane strength and elasticity, indicated by the stress and strain values. XRD data showed membrane has a crystalline structure, and SEM data showed microsphere size of the membrane, and (3) The filtration capability of the membrane was showed by the data profile of urea absorption.
