Pervaporation separation of a water/ethanol mixture by a sodium sulfonate polysulfone membrane

Abstract: A sodium sulfonate polysulfone membrane was prepared for the dehydration of a water/ethanol mixture by pervaporation. The separation performances of water and ethanol were examined by the testing of the ethanol/ water mixture under operating conditions. The permselectivity of the sodium sulfonate polysulfone membrane was found to strongly depend on the sodium content in the membrane. The sodium sulfonate ratio showed a significant influence on the hydrophilicity and diffusion behavior of the polysulfone membra… Show more

“…Since polysulfone (PSF) membranes have high mechanical property, good heat-aging resistance and chemical stability, they have been widely used in various fields involving food processing, water treatment and biotechnology [1,2], especially in the aspects of micro-/ultra-filtration, gas separation, pervaporation, hemodialysis, plasma separators, membrane oxygenators, cell culture, bioartificial organs [3][4][5][6][7][8][9][10]. However, due to the hydrophobic nature of PSF material, conventional PSF membranes easily suffer serious membrane fouling and have low permeation flux, making it undesirable in the filtration of protein containing solution and blood-contact applications.…”

“…The PSF membranes could be modified by sulfonation or sodium substitution leading to increase in both separation factor and flux of the resulting sulfonated PSF membranes and sodium sulfonate PSF membranes (Hung et al, 2003). Some of these PSF-based membranes have both high separation factors (>200) and high flux (>0.6 kg m ±2 h ±1 ) (see Table 10.3).…”
