EFFECT OF UV-LIGHT ON DIFFERENT STRUCTURAL AND TRANSPORT PARAMETERS OF CELLOPHANE MEMBRANES

A comparative study of UV light influence on structural and transport parameters of cellophane membranes was made. Changes in the chemical s tructure and electrical behavior of cellophane membranes were consider ed by determining the hydraulic permeability, salt diffusion coefficie nt, and resistance values, as well as some geometrical parameters, for an untreated membrane and two differently UV-treated cellophane membr anes. Differences in the characteristic parameters for the three sampl es showed that radiation mainly affected the membrane structure, while only small changes in membrane electrical behavior were determined.
