Abstract

Xylose is the raw material for xylitol production which can be obtained through hydrolysis of agriculture waste. However, the
presence of glucose in hydrolysate interferes in the process. Thin-film composite membrane developed through interfacial
polymerization (IP) can be tailored for xylose separation through manipulation preparation conditions. In this study, the impact
of curing conditions, specifically curing time was investigated on xylose separation. The thin-film composite (TFC) membrane
was formed from IP between triethanolamine (TEOA) and tri-mesoyl chloride (TMC) on polyethersulfone support membrane.
Attenuated Total Reflection Fourier Transform Infrared (ATR-FTIR) spectroscopy and contact angle measurement were performed
to investigate the formation of thin-film. Evaluation of membrane performances, namely pure water flux, permeation flux, and
xylose separation factor was used to evaluate the TFC membrane cured at a different time (2, 5, 10, 15, and 20 minutes). A decrease
in flux was observed when prolonged the curing time for TFC membrane. A minimum of 5 minutes curing time would be needed for
the organic solvent to be evaporated from the membrane at 60 oC, but 15 minute curing time would have better xylose separation.
