Separation of bioethanol using in situ composite membrane of bacterial cellulose/poly (2-acrylamido-2-methylpropane sulfonic acid) (AMPS) and their characterization

Abstract In the current study, bioethanol has been purified and separated from culture broth using in situ modified bacterial cellulose (BC) membrane with AMPS. To our knowledge, this is first report for development of BC composite separation production media. The characterization prepared was investigated morphology functional groups via scanning electron microscopy (SEM), Fourier transform infrared (FT-IR) spectroscopy, Raman addition to determination their water ethanol uptake. obtained data proved formation multilayers existence its specific function groups. Amicon cell pervaporation system containing BC/AMPS used nitrogen gas pressure, results revealed that more efficient than neat process bioethanol. At 50-psi best factor flux were recorded as 15.43 98.94 g/m 2 .h, respectively, which accompanied by elevation concentration 1.98 3.22 mg/ml before after separation, respectively. These findings promising application field bioenergy especially separation.
