Polyacrylonitrile membranes are prepared using three different membrane preparation principles. Characterization of the structure of the skin layer is carried out in more detail by parameters of separation curves and their pore sizc distribution function, the former being based on a logarithmic norm
Zeolite NaA membranes have been synthesized by secondary growth on the external surface of β£-alumina tubular supports using a semicontinuous system in which fresh gel was periodically supplied to the synthesis vessel. Compared to traditional batch methods, the procedure developed in this work provid
