In the present study, catalytic activity of dense, porous, electrospun membranes polysulfone (PSF) and with sulfonated polystyrene (PSF_PSS) have been evaluated in reactions esterification oleic acid methanol, times that varied from 10 to 480 minutes. Conversion biodiesel has confirmed by FTIR quantified through gas chromatography. The results showed catalysts used were effective reaction studi...

This study aimed to investigate the effect of Gadolinium oxide (Gd2O3) concentration (0.5%, 1%, and 2%) on performance polysulfone (PSF) membrane. The membranes were fabricated by a common phase inversion method. was determined based pure water flux, bovine serum albumin (BSA) permeation test. These characterized FTIR contact angle measurements. highest BSA rejection 53%. optimum membrane (2 % ...
