Abstract
Mixed matrix blend membranes (MMMs) of sodium alginate-hydroxy propyl cellulose (SA-HPC) were prepared
by loading with phosphomolybdic acid (PMA) and characterized by various physico-chemical techniques
like Fourier transform infrared spectral, scanning electron microscopy and thermo gravimetric analysis.
Pervaporation properties of membranes were investigated for the separation of water-isopropanol feed mixtures
containing 10-15 wt.% of water. Membrane performance showed dependence on the extent of PMA loading. The
0.2 wt.% PMA-loaded blend membrane had the highest selectivity of 1865, which declined considerably at higher
loading. The flux of 0.2 wt. % PMA-loaded membrane was higher than that of pristine SA-HPC blend membrane.
Degree of swelling was smaller after PMA loading exhibiting better separation ability. From this study, it is
concluded that the selectivity of MMMs is higher than the pristine SA-HPC blend membrane.
