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 with a value of 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.

Abstrak

Peranan surfaktan dalam pembentukan ultraturasan PVDF aktif (AUF) membran telah dikaji. Gabungan kesan surfaktan iaitu SDS/Tween 80 dan Tween 80/Triton X-100 formulasi terhadap prestasi dan struktur morfologi telah dikaji buat pertama kali. Pengaruh adunan surfaktan pada liang membran juga diperiksa. Data ujikaji menunjukkan bahawa gabungan Tween 80/Triton X-100 memberikan bacaan penyerapan fluks tertinggi iaitu 285.51 Lm^-2h^-1. Dengan kombinasi SDS/Tween 80, membran AUF menunjukkan protein penolakan tertinggi sehingga 93 % dan 79 % masing – masing untuk Albumin Serum Bovine (BSA) dan Albumin Telur (EA). Selain itu, membran pencirian menunjukkan bahawa penambahan SDS/Tween 80 dan Tween 80/Triton X-100 didapati memberi kesan kepada prestasi, morfologi permukaan dan liang membran AUF PVDF.
