Abstract

A procedure for the controlled barrier layer removal is suggested in this work which provides the preparation of anodic alumina membrane with specified pore diameter and permeance. Optimal conditions for barrier layer removal which give membranes with high gas permeance of 400 m³/(m² atm h) by nitrogen and breaking strength of up to 440 ± 40 MPa, which is allowable for their operation in baromembrane processes, are developed.
