Organic vapours such as ethyl methyl ketone, methyl-alcohol and acetaldehyde were adsorbed on the alumina gel between 273 K-298K under vacuum of 10(-4) to 10(-5) mm Hg, achieved by rotary and oil diffusion pimps. Cahn 1000 electro-microbalance and X-Y Beckman chart recorder were used for recording the data Kinetic parameters such as rate constant, Knudsen diffusivities, bulk diffusivities and effective diffusivities were evaluated through Fick type equation. The effect of temperature on the sorption of these organic vapours has also been discussed.
