In the application of the method proposed in the previous papers to real water-vapour adsorption measurements it has been found to be confronted with a few difficulties as follows : 1) It takes long time to determine a full absorption isotherm. 2) Several samplings are indispensable to obtain a full adsorption isotherm so that the measurement will be attended with sampling errors. 3) The changes in the surface properties of the sample may be involved in consequence of the repetition of adsorption/desorption cycles. So in this paper, the authors give the new method based on the conventional volumetric method, which has the blank test as an improvement to determine the full adsorption isotherm of water-vapour on the used grease and the used oil. By means of this method the precise and accurate adsorption isotherm of water-vapour on the zinc oxide powdery sample is obtained without the above-mentioned difficulties.
