| Annotation |
Nylon, cellulose acetate, and polytetrafluoroethylene (PTFE) membranes are subjected to ultra-
violet irradiation in the wavelength range of 280–320 nm to improve their performance in separation of oil-
in-water emulsions. The mass of membranes is found to change in relation to the duration of irradiation. The
wettability of the surface layer of the PTFE and nylon membranes improves. Alterations of the supramolec-
ular structure of membranes are demonstrated by Fourier-transform IR spectroscopy: the intensity of
absorption bands in IR spectra increases in the range of 600−3600 cm –1 . UV irradiation has an effect on the
key parameters of membrane separation of a model oil-in-water emulsion using the considered membranes:
the specific performance of nylon and cellulose acetate membranes increases by up to 7% depending on the
duration of UV irradiation, whereas a 14% decrease in specific performance and a 14% increase in the effec-
tiveness of emulsion separation are observed for the PTFE membrane. |
