Abstract

ABSTRACT This study investigated the effects of Arabic gum (AG) on the separation performance of polyvinylidene fluoride (PVDF) membranes. The membrane properties were characterized using scanning electron microscope energy dispersive X-ray (SEM–EDX), Fourier transforms infrared (FTIR), tensile strength tester, and contact angle. Results showed that incorporating AG from 0.5wt% to 1.5 wt% into PVDF membrane could increase pure water flux from 47.46 L/m2 h to 66.04 L/m2 h and porosity from 53% to 58%. Moreover, the highest flux recovery was obtained by PVDF/AG-1.5 membrane, revealing the improvement in fouling resistance against bovine serum albumin (BSA). However, the addition of AG from 0.5wt% to 1.5 wt% did not affect to increase of membrane mechanical strength and the efficiency of the membranes for BSA rejection. SEM, XRD and FTIR analyses confirmed the successful incorporation of AG, which improved membrane surface hydrophilicity compared to the pristine PVDF membrane. Overall, the obtained result showed that incorporating AG could attain synergy benefits in enhancing the membrane properties and performance.
