At present work the data on sorption of acetonitrile and water by GO powder and two GOMs, manufactured from this powder, was obtained, and compared with the orientational order of GOMs. Ordering of the graphene oxide layers in the membranes was determined using spin probe technique according to the method which was worked out in our scientific group. GOM, manufactured by evaporation of GO suspension, turned out to be practically not aligned; and sorption of acetonitrile and water by this GOM and GO powder was the same. GOM, manufactured by filtration of GO suspension, was oriented with the order parameter P20=0.21; sorption of water by this GOM was the same as by GO powder, but sorption of acetonitrile was zero. Based on the experimental data, the following conclusions can be made. Firstly, the orientational order of GOM depends on manufacturing method. Secondly, sorption seems to be in connection with orientational order of GO layers inside the membrane.
