The sorption of carbon tetrachloride at low pressures by activated charcoals. Part II.—isothermals at 25° C

Abstract

The experimental methods employed in this work were described in part I, and nothing will be added beyond reference to special points of importance in the particular experiments concerned. As the data obtained have no absolute significance, diagrams will be usually employed to the exclusion of tables of results. This method has the additional advantages of making the relations observed more immediately obvious. The data will, in general, be plotted in the form of the logarithm of the tetrachloride charge(milligram per gram charcoal) against the logarithm of the carbon tetrachloride pressure (millimetre of mercury). (1) Directly Determined Isothermals The experiments will be described in the order in which they were done with a view to making more clear the reasons for the modifications in experimental procedure adopted as the work proceeded.
