Abstract This study investigated the separation of bovine serum albumin using a novel matrix mixed membrane composed poly vinyl pyrrolidone and (phenylene ether sulfone)/Nano-silver. The responsive bare modified PEES/Nano-silver membranes were evaluated morphology, wettability, XRD ATR-FTIR. molecular weight cut-off (MWCO), water content, mean pore radius, porosity, pure flux used to evaluate p...
