چکیده
|
The separation of demethylsolfoxide mixture from aqueous solution, is carried out by pervaporation membrane process# the pbax-2533 membrane was synthesized by the solution casting and solvent evaporation method# the prepared membrane was characterized by fourier transform infrared spectroscopy (ftir) and scanning electronic microscopy (sem)# the flux of the membrane and the swelling degree were examined for the separation of dimethyl sulfoxide from their aqueous solutions (5, 10 and 15 wt# %)# results showed that total permeances for the prepared membrane were increased with increasing the amount of dmso in the feed mixture# the maximum permeance was found to be 1#21 kg/m2 h at 25 oc#
