Abstract
Alumina asymmetric ceramic membranes were prepared by sol–gel method. Research on structure of alumina membrane active layer is conducted by methods of physical nitrogen adsorption and small-angle scattering of synchrotron radiation, the obtained data confirms and supplements each other. Surface area for the studied material varies from 255 to 264 m2/g, average pore diameter varies from 5.3 nm to 5.4 nm.
