Activated composite membranes (ACMs) containing the chiral carrier
N-hexadecyl-

nica(IFME) program, and certain morphological properties of the ACM (such as mean internal poresize, internal irregularity, and internal asymmetry) were determined. In addition, ACMs havebeen tested for propranolol filtration, using a dead-end filtration membrane module workingunder 3.5 bar, and both the permeation rate and the enantioselectivity have been evaluated.Propranolol permeation through the three ACMs has been detected here; however, unfortunately,a clear enantioselective behavior has not been observed. The morphological structure of theACM has been studied and related with their obtention procedure. Resulting data were finallycompared with the results from other characterization techniques applied previously for suchmembranes.
