Abstract
The role of surfactants in the formation of active Poly (vinylidene fluoride) (PVDF) ultrafiltration (AUF) membranes was studied. The effect combination of surfactants that are Sodium dodecyl sulfate (SDS)/Tween 80 and Tween 80/Triton X-100 formulations on performance and morphological structures were investigated for the first time. The influence of surfactants blends on the membrane pores was also examined. Experimental data showed that combination of Tween 80/Triton X-100 give the highest BSA permeation flux which value 285.51 Lm-2h-1. With combination of SDS/Tween 80, the AUF membrane showed the highest protein rejection up to 93% and 79% for Bovine Serum Albumin (BSA) and Egg Albumin (EA), respectively. Moreover, membranes characterization demonstrated that the addition of SDS/Tween 80 and Tween 80/Triton X-100 were found to affect the performance, surface morphologies and membrane pores of AUF PVDF membranes.
