Abstract
Penelitian ini bertujuan untuk meningkatkan kinerja
membran ultrafiltrasi selulosa asetat (CA) dengan
penambahan polietilen glikol (PEG) 400 dan sulfonasi.
Membran dibuat dengan metode inversi fasa rendam endap.
Membran yang dihasilkan dikarakterisasi dengan FTIR dan
SEM, serta diuji fluks air dan rejeksinya terhadap pewarna
merah Kongo pada tekanan 2 bar. Membran CA mencapai
kondisi optimum pada konsentrasi CA sebesar 17,5% (b/b)
dengan fluks air sebesar 13,57 L/m2jam dan rejeksi sebesar
91,08%. Penambahan PEG 400 sebanyak 2% (b/b)
meningkatkan fluks air hingga 16,51 L/m2jam, sedangkan
sulfonasi selama 120 menit meningkatkan rejeksi hingga
91,33%.

The purpose of this research is to improve cellulose
acetate (CA) ultrafiltration membrane performance by adding
polyethylene glycol (PEG) 400 and sulfonation. Membranes were
fabricated by immersion precipitation phase inversion method.
Fabricated membranes were characterized with FTIR and SEM,
while their pure water flux and rejection towards Congo red were
tested at 2 bar. CA membrane achieved its optimum performance
at 17,5% (w/w) of CA with pure water flux of 13,57 L/m2h and
rejection of 91,08%. Addition of 2% (w/w) PEG 400 improved
pure water flux to 16,51 L/m2h, meanwhile 120 minutes
sulfonation improved rejection to 91,33%.
