Diffraction research of porosity of cellulose acetate membrane MGA-95
Keywords:
membrane, pores structure, sorption ability, amorphousness, inertia radiuses.
Abstract
Method of X-ray diffraction was used for research of sorption regions of air-dry, water-saturated and working samples of a semipermeable membrane MGA-95. Comparative analysis of the diffraction patterns of new and working membrane's samples shows that factor of external influence plays only a catalytic role in the transport of material, but not on the intramolecular structural changes in base of cellulose acetate semipermeable membrane. There was found the structure of membrane MGA-95 pores by smallangle X-ray scattering, which was calculated from the position of the fractal concept, where there are three kinds of pores (sphere, disc, cylinder) and determination of their average inertia radius.
