A study on krypton adsorption on uranium dioxide kernels

Abstract

The monolayer capacity in the physical adsorption of krypton or point B, i.e. the point defining the beginning of the plateau region of the S-shaped isotherm, was used to determine the number of statistical layers $\text{n}\text{V}\text{V}{}_{\mathrm{m}}$).

In the absence of capillary condensation, the V−n plot was a straight line with slope $\text{V}\text{n}$ or V_m. When extrapolated to V = 0, this line intersected the axes at the origin. The two conditions that the data points fit a straight line and that this line may be extrapolated to the origin combine to make a V−n plot a rigorous test for both the accuracy of the n values and the isotherm data.
