Apparent adsorption isotherm equations have been derived from the solution on the ultrafine powders on the basis that the solution is of perfect solution, that the component molecules have sizes different from each other, and that there is no interaction between the admolecules in the adphase. The shape of these calculated isotherms exhibits the general features of experimental apparent adsorption isotherm. The surface areas obtained from these equations show reasonable agreement with the BET surface areas from the separate experiment on the vapour phase adsorption with single component.
