%! Diffusion and Flow of Water Vapours in Chromatographic Alumina Gel
%K
%X The kinetics of sorption of water vapours in chromatographic alumina gel was studied. Water vapours are adsorbed on the gel at temperature (15 °C) at different constant relative pressure from 0.1-0.93 p/p. Rate constant, Effective diffusivities, Knudsen diffusivities and bulk diffusivities were determined through Fick type equation. Total pore volume is 0.498 cc g-1 and specific surface area comes to be 465 m2 g-1 as obtained by Gurvitsch rule and Kieselve’s equations respectively. An average pore radius (hydraulic) is 1.1x10-7 cm. The study of these quantities provide a strong basis for evaluating surface properties.
