Abstract

Heats of adsoption for a series of hydocarbons on Laponite-RD clay were determined by two gas chromatographic methods. The first method was an extension of packed column gas-solid chromatography. The second method employed a novel wall coated open tublar (WCOT) that was prepared from clay aqueous suspensions. The two different methods of preparing chromatographic columns are discussed in this paper, and a comparison between the results obtained on the two systems is made. We conclude that the WCOT method provides the same thermodynamic results as does the conventional packed column method, while offering some difinite improvements in the measurement process and data behavior.
