چکیده
|
In this research work, porous pes membranes were initially pre-heated for certain duration of time and then surface-modified to reject the mgso4 salt solutions through self-adsorption of polyelectrolytes. from the experimental work, higher membrane salt rejection capability can be obtained when the number of polyelectrolyte bilayers is increased. the images of the cross-sectional morphology of modified and non-modified membranes were obtained using field emission scanning electron microscopy (fesem). all modified membranes showed relatively lower contact angle values.
